So Larry Fitzgerald is coming back, a boon to the Cardinals -- at least for 2017. After moving on from Michael Floyd (which was probable as 2016 moved on and Floyd heading into free agency, regardless of his off-field issues), the Cards needed a Fitz anchor at wide receiver. But for the long-term, does it change a lot? The Cardinals still need to consider a big receiver in the draft, I'd think, a guy who can help fill the Fitz void when that comes sooner rather than later (and the way this all has gone, it feels like Fitzgerald is going to want to hang it up after 2017.)
Again, the biggest question after Fitzgerald when it comes to wide receiver is the ability for Smokey Brown to return to form. If Brown is able to play next season like he did for most of 2015 (Brown did battle hamstring issues that year and it might have been the sickle cell issue), the Cardinals should be fine. J.J. Nelson was emerging the last part of the season. Again, there probably needs to be a long-term "big" receiver plan post-Fitz, but it's not crucial. The return of Fitz does ease the pressure -- and eliminates a potential hole -- that could have forced something different at the 13th overall pick. Then again, if Clemson's Mike Williams is still on the board ...
(Besides, good passing games come down to the quarterback often. If Carson Palmer retires along with Fitz, the Cards' QB situation will be priority 1, 2 and 3. And probably 4 and 5.)
No, you don't forget running back David Johnson either. He'll play a huge role in the passing game again, I am sure. But again, if Brown and Jaron Brown (torn ACL) can come back healthy, along with Fitz and Nelson, the Cardinals' receiving corps should be fine for this season.
