Fantasy Football Trade Tips: Why it's time to deal Puka Nacua before it's too late, plus 4 players to buy

Creating realistic trade offers that lead to a deal being accepted is always challenging. Throughout the season, Justin Boone will be publishing his rest-of-season trade value charts, which you can use as a guide to help make moves and manage your roster. Below he highlights some of the players you should be buying or selling, before their value shifts in the coming weeks.

Waddle has been disappointing through the first month with just one big fantasy performance in a Broncos' jersey (8-138-1 in Week 2). He's been held to 35 yards or less in the other three contests, but was able to salvage his Week 4 stat line with a late touchdown.

Fantasy managers are understandably frustrated, since this was a player taken in the first four rounds who came with the promise of being a top-24 wideout. At the moment, Waddle sits at WR32 in fantasy points per game.

Fortunately, a few things are lining up for him moving forward. His teammate Pat Bryant, who has put up at least 40 yards three times this season, suffered an ankle injury that could sideline him for multiple weeks — freeing up more targets for Waddle.

The Broncos have also struggled to find their offensive rhythm in the opening month against four Super Bowl contenders in the Chiefs, Jaguars, Rams and 49ers. The Chargers will be a much easier opponent this week. Waddle even had success against them last year, posting six catches for 95 yards as a member of the Dolphins.

Denver's dominant secondary is also dealing with injuries to Patrick Surtain II and Riley Moss, which could create more high-scoring gamescripts. If you can get Waddle for WR3 value right now, it's worth buying low.

Tuten doesn't fall under the buy-low category, instead he should be considered a buy-high target because the ceiling hasn't been reached yet.

The 23-year-old is the RB16 on the year, with double-digit fantasy points in three straight games. His role continues to grow after season-highs in snaps (59%), touches (19) and scrimmage yards (91) in Week 4. Those numbers could have been even better if his two touchdowns in the game actually counted. Tuten scored from 44 yards and three yards, but both were called back due to holding penalties.

We're on the verge of a massive game from Tuten one of these weeks. He's also showing strong consistency by topping 85 yards in three of four games. This is a young explosive back who's dominating work in one of the best offenses in the league.

Don't wait for the monster stat line to arrive, see if you can acquire him before it occurs.

While I'm not expecting Hall to return in Week 5, it's worth checking to see if his manager has a losing record and needs immediate help. The uncertainty around Hall's recovery timeline from the quad injury can leave managers in limbo as the losses pile up and they might be willing to part with him at a discount.

Since he wasn't placed on injured reserve, it would be surprising if he sat out more than another week or two. And remember how well he was performing before the injury.

Hall went off for 118 yards and a touchdown on 24 touches in the opener, then followed that up with 92 yards on 21 touches in Week 2. The Jets also have a fairly favorable schedule the rest of the way.

Don't overreact to last week's embarrassing outing, where the Bears controlled the game from start to finish and stifled New York's offense for the entire afternoon. Better days are ahead for the Jets and they'll start when Hall gets back on the field. From that point on, he'll be a high-end fantasy RB2 with RB1 upside.

So, if your team is doing well and you can handle keeping him on your bench until he's healthy, you should think about making an offer.

This one is a little more speculative than normal, but it's something worth getting ahead on just in case we get bad news on Rhamondre Stevenson this week.

Injury analyst Jeff Mueller of Fantasy Points, noticed Stevenson got banged up near the end of the Patriots win over the Bills on Sunday. He eventually limped to the sidelines.

That alone would just be something to monitor, but when you combine it with the Pats bringing in veteran Jamaal Williams for a visit, the alarm bells start going off.

Henderson showed last year what he can do in the lead back role. From Week 8 on, with Stevenson missing three contests, Henderson showcased high-end fantasy potential as the RB12 during that stretch, including two games with at least 150 yards and two scores.

It would also be an ideal time for Henderson to take the reins, as New England's schedule is lightening up after opening the season against the Seahawks, Steelers and Jaguars' run defenses.

I wouldn't recommend overpaying for Henderson until we know exactly what Stevenson is dealing with, but you might want to explore making a quick trade in case Stevenson's injury costs him time.

Trading away a major part of your fantasy lineup is never an easy decision, but one good game doesn't erase Nacua's injury concerns. While he returned to play 91% of the snaps and racked up 127 scrimmage yards and a touchdown, this situation still feels like it could unravel at any moment.

On the broadcast, FOX's Erin Andrews reported that Nacua has been dealing with a pre-hernia injury. Given his performance in Week 4, it's possible that Nacua could manage the issue and associated pain, while continuing to play the rest of the season.

However, it's also possible he could aggravate the injury and miss more time or eventually require surgery.

Personally, I don't want one of the most important pieces of my fantasy roster carrying that kind of risk. If you can capitalize on his big stat line and get WR1 or RB1 value for him, I'd be doing that immediately.

Love appeared to be on a clear breakout path after Week 3, which featured season-highs with 26 touches, 109 scrimmage yards and a touchdown on a 64% snap share against the 49ers.

Sadly, Week 4 left us with more questions than answers. The rookie's usage dipped back down to 46% of the snaps, 15 touches and just 55 scrimmage yards.

He sat out the end of the game and was very candid with reporters in the locker room after, suggesting that his preseason ankle injury isn't the only thing he's dealing with and that this is going to be the "longest year" of his life.

The whole situation leaves an air of uncertainty around Love's outlook, since it sounds like he won't be taking on a larger workload most weeks. Instead, Tyler Allgeier will remain heavily involved.

The matchup with the Lions is a positive one in Week 5, but the Cardinals' schedule tightens up after that with the Rams, Broncos, Seahawks, Rams and Chiefs in five of their following six outings.

Arizona also doesn't have a bye until Week 14, so there won't be much time for Love to rest and heal from some of these early season injuries.

I'm viewing Love more as a volatile low-end fantasy RB2, so if you can get a more stable asset back in a trade, it's time to make that move.

It's been incredible to watch Samuel reach at least 15 fantasy points in three of his first four games since rejoining the 49ers this offseason. The 30-year-old is currently WR15 in fppg, but I have my doubts that he'll be able to sustain this level of production.

In addition to potential age-related decline as the season progresses, we also need to take a real look at how Samuel has scored his fantasy points. Three touchdowns have been a big part of his success so far, including an 80-yard hook-and-ladder that he took to the house. Most weeks when a receiver has (checks notes) zero targets, he isn't likely to come away with 80 yards and a score.

Injuries have also paved the way for Samuel, but Christian Kirk could be activated from IR soon and rookie De'Zhaun Stribling is expected back down the stretch.

If you want to keep riding Samuel's early-season stats and hoping he can continue to drink from the fountain of youth, I won't stop you. But I'm trading him away for younger players who I have more faith in over the course of the entire season.

Kamara hasn't been the same running back for the last couple seasons, which shouldn't shock anyone given his age. The 31-year-old has lost a step (or two), but that doesn't mean he can't take advantage of high-value touches when he gets them.

With Travis Etienne Jr. on IR, Kamara handled seven carries and seven targets touches on Monday night, turning them into 58 yards, five receptions and two touchdowns.

The prime time performance, which made him the RB10 on the week, will surely be his highpoint of the season from a fantasy perspective. Even as the starter, he only played 38% of the snaps. There is no way Kamara keeps this up.

You need to move fast and package Kamara in an offer with another piece to upgrade your lineup. His name value combined with the Week 4 fantasy points should be enough to entice at least one RB-needy manager in your league.
