Trading is a huge part of fantasy Football, and it's even more important after week 2, as the true value of players starts to become more clear. David Johnson is off to an awful start. Jordan Howard is struggling. Highly drafted wide receivers like Odell Beckham Jr. are having trouble scoring fantasy points. But that doesn't mean their struggles will continue in the future. It's time to take advantage of frustrated fantasy owners and make some trades for players who are clearly undervalued right now.

1. Atlanta Falcons RB Devonta Freeman

The Falcons offense got off to a rough start in week 1 against the Eagles, but returned to prominence with a huge game against a good Carolina Panthers defense.

That week 1 game was likely a fluke, and once Freeman returns from injury, he will again be at least a top 15 fantasy running back. With Freeman injured, other fantasy owners will be more than willing to accept trades for him.

2. Arizona Cardinals RB David Johnson

Johnson is off to a tough start, but he's still averaged eight fantasy points per game in his first two matchups. The Cardinals offense is so horrible that it's difficult to believe Johnson will return to prominence, but Johnson has the talent to live up to his draft position. If Josh Rosen does eventually become the starter, Johnson will be even more valuable as the rookie quarterback looks to his running back as a safety blanket.

3. Seattle Seahawks QB Russell Wilson

Does anybody remember what happened last year with Wilson? His year started off horribly, with two games of less than 200 yards passing. He passed for just one touchdown combined in those games and did not rush for a touchdown. Wilson ended up finishing the 2017 season as the highest scoring overall fantasy quarterback.

At this point, fantasy owners should be looking to trade for Wilson, who has played two elite defenses on the road to start the year in the Denver Broncos and the Chicago Bears.

4. Chicago Bears WR Allen Robinson

Robinson isn't off to the best start in the world, but he did catch 10 passes for 83 receiving yards against the Seahawks on Monday night.

Trubisky loves to throw to Robinson, as evidenced by that reception total, and that makes Robinson a valuable fantasy player moving forward. Robinson's average fantasy points per game of 7 should increase as Robinson starts to get more involved in the red zone.

Keep in mind that these players haven't performed at a level like Tyreek Hill or Stefon Diggs. That should offer fantasy owners opportunities to make great deals for undervalued players like Devonta Freeman, David Johnson, Russell Wilson, and Allen Robinson.
