Not quite the NFC superpower they used to be, but with a new QB, the return of David Johnson, and a living legend in Larry Fitzgerald, the Cards have some potential for explosive plays.
DJ is not only one of the best HBs in Madden 19, he's also arguably the most balanced. A quality rusher with excellent ball carrier moves, DJ is a skilled route runner and pass catcher, too. Use him as much as possible.
There isn't a lot of depth at WR beyond Fitz, who is better suited at the slot position and is among the surest hands in the game. J.J. Nelson and Brice Butler, though, are both speedsters, and are more vertical threats, but they might not get the seperation you want to take it deep.
Sam Bradford and rookie Josh Rosen are your two real options here. Bradford has deep accuracy and is better under pressure, while Rosen has more Throw Power, a higher Break Sack rating, and better accuracy numbers at the short and mid ranges. Rosen might be the play.
Patrick Peterson possesses two unique talents. Not only is he a Pro Bowl corner, but he's electric with the ball in his hands. One INT can turn to an easy TD with the right stick skills.
Budda Baker is a quality user controll option. At a 79 OVR, he's not on anyone's radar. He has solid Catch and base ratings scores, but what puts him so far down are his poor ratings in Man and Zone Coverage.
If you're more of a Hit Stick specialist, ROLB Deone Bucannon is for you. His 92 Hit Power is the tops on the team, and he has enough Speed to sniff out the ball carrier.
