Fantasy Upside
J.J. Nelson enjoyed a bit of a breakout during the second half of the 2016 season, but he benefited from quite a few splashy plays and caught only 34 passes on the season. After playing sparingly behind Larry Fitzgerald, Michael Floyd, and John Brown, Nelson was a near-every-down player and racked up 9.7 targets per game during the final three games of the season. As ESPN.com noted, Nelson's 16.9 average depth of target was highest among players targeted at least 50 times. The 2015 fifth-round pick is undersized at 5-foot-10, 160 pounds, but boasts game-breaking 4.26 speed.
Fantasy Downside
It's a crowded field if all involved—including David Johnson, who in addition to his running back duties is also the team's de facto No. 2 WR—are healthy and playing their usual roles. Carson Palmer will need to be on his game and he'll have to spread the ball around to fuel everybody's fantasy needs.
2017 Bottom Line
Fitzgerald turns 34 this year, Floyd is gone, and Brown struggled with health issues all last season, so Arizona added Chad Williams in the third round of April's draft. But the newcomer is viewed more as an eventual replacement for Fitzgerald than an immediate impact receiver this year, so Nelson's chances of playing a significant role in 2017 are reasonable.
