Working the Fantasy football trade market is a great way to rapidly improve your Fantasy football roster, but you're also at risk of making your team worse and giving a rival a leg up when a trade goes wrong. If you traded for Jeff Wilson after he produced four consecutive games with at least 74 rushing yards with the 49ers last season, chances are you felt burned when San Francisco traded for Christian McCaffrey a week later. Wilson was himself traded to the Dolphins, while McCaffrey was an ideal fit in the San Francisco offense and has reestablished himself as a Fantasy football powerhouse.

Having a list of buy-low and sell-high candidates can help ensure that you get maximum value out of any Fantasy football trades you might be considering.

Top Week 4 Fantasy football buy-low, sell-high candidates

One of Kaylor's top buy-low candidates is Broncos quarterback Russell Wilson. Rarely does a 50-point loss bring about any positives after Miami dominated Denver, 70-20, last week. But for Fantasy football, a one-sided score still gives the opportunity to be fantasy-relevant. Wilson threw for 306 yards and a touchdown and is the No. 9 quarterback in Fantasy football through three weeks.

Wilson has thrown for at least 300 yards in each of the last two weeks as he's still adjusting to playing in Sean Payton's system. Wilson reached 300 yards in his first game in Denver last season and never again over his final 14 contests. The nine-time Pro Bowler is completing nearly 5% more of his passes this season than last (65.4% compared to 60.5%) and already has six touchdown passes after only posting 16 scores last year. Even though the Broncos are off to a 0-3 start, Wilson is performing like a capable Fantasy football starter. Kaylor is recommending either a QB2 swap or even giving up a high-end RB3 or WR3 to snag the veteran.

Kaylor is also advising Fantasy football managers to sell high on Chiefs tight end Travis Kelce. The All-Pro tight end has never been more famous now that he's been linked publicly with megastar Taylor Swift. Kaylor's reasons for selling high, however, are more linked to on-field factors that you might be overlooking. 

He has only averaged 8.6 yards per reception this season, and without the garbage-time touchdown that he scored last week against the Bears, he'd rank just ninth among Fantasy football tight ends. This Chiefs offense took advantage of a terrible Bears defense but has looked underwhelming otherwise, and that's why Kaylor is recommending moving Kelce for a high-end WR1, high-end RB1, or a combination of WR1 and RB2 or vice versa. For more buy-low and sell-high candidates, be sure to check out the rest of the Week 4 Fantasy football trade values at SportsLine.
