This is a list of the top 10 players whose fantasy stock has increased because on what happened in free agency and the draft. This report will be reflected in the overall rankings, which will be updated soon. Here's a link to the Fantasy Football Stock Down page.
There will be many more 2015 Fantasy Football Rankings and features in the late spring and summer, including tons of 2015 Fantasy Football Mock Drafts, Player Rankings, Sleepers and Busts. I'll also have an extensive 2015 NFL Fantasy Football Preseason Stock Report.
2015 Fantasy Football Offseason Stock Report (Up)
10. Eric Decker, WR, Jets
Eric Decker would have loved an upgrade at quarterback, but didn't get one. So, why is he on this list? Because he was the only prominent receiver in the AFC East to benefit from the cornerback musical chairs in free agency. The wideouts in Miami and Buffalo still have to deal with Darrelle Revis, but Decker doesn't anymore. That's a two-game upgrade for him.
9. Owen Daniels, TE, Broncos
Owen Daniels signed with the Broncos this offseason. It was a great move, as he'll have a high chance of being very productive with Peyton Manning throwing the ball to him. Daniels is obviously familiar with Gary Kubiak's offense, so there won't be a learning curve. The only issue with Daniels is his durability.
8. Darren McFadden, RB, Raiders
It's unclear how Dallas' running back rotation will shape out, but it seems as though Darren McFadden will be No. 2 on the depth chart behind Joseph Randle. If he makes the roster, he'll be worth picking up because of how good the Cowboys' offensive line is.
7. Frank Gore, RB, Colts
Frank Gore is now 32, but he'll have a starting job next season because he rushed for 1,106 yards in 2014. Gore could be in position to score plenty of touchdowns in Andrew Luck's offense.
6. Jordan Matthews, WR, Eagles
Jordan Matthews generated most of his production with Mark Sanchez, as the former Jets' quarterback preferred throwing the ball to him, so it doesn't matter too much that Nick Foles is gone. If Sam Bradford gets injured, Matthews can pick up where he left off with Sanchez. And with Jeremy Maclin now in Kansas City, Matthews' outlook is extremely bright.
5. Russell Wilson, QB, Seahawks
Russell Wilson was a great fantasy option last year because of his rushing numbers. He scrambled for 849 yards and six touchdowns. It's unrealistic to expect him to rush for that much yardage again, but perhaps his passing numbers will be better in 2015 with Jimmy Graham now on the roster.
4. Andre Johnson, WR, Colts
Andre Johnson hasn't caught more than five touchdowns since 2010, but perhaps that'll change now that he'll get to play with a top-level quarterback for the first time in his career. Johnson, 34 in July, is still set to decline soon, but maybe he'll be able to have one good season in Indianapolis.
3. Joe Flacco, QB, Ravens
Joe Flacco just had his best statistical season, throwing for 3,986 yards, 27 touchdowns and just 12 interceptions. Torrey Smith is gone, but Flacco's outlook is bright, given that the team hired Marc Trestman, who is also known as the "quarterback whisperer." Baltimore also spent its first two selections on offensive weapons. Flacco will be a borderline QB1 this year.
2. Brandin Cooks, WR, Saints
Brandin Cooks missed the second half of the season with a thumb injury. Before that, he was a constant PPR producer, catching 53 balls for 550 yards in 10 games. He only scored four touchdowns, but that number, as well as his other figures, could rise exponentially with Jimmy Graham and Kenny Stills both gone.
1. Joseph Randle, RB, Cowboys
Joseph Randle was facing charges for a domestic disturbance, but he was cleared in late April. He's now the favorite to lead the Cowboys in touches, though he could be splitting the workload with Darren McFadden and Lance Dunbar. Randle has tremendous upside because of how great Dallas' offensive line is.
