PFT is just basing things off last year, where Allison was a non-factor to them because he didn't get enough snaps for them to grade him and they fail to factor in part of what held MVS back was that he was a rookie #2 with almost zero chemistry and little trust from his QB which strongly factors trust I to his throws.
So if MVS will get a lot better if he simply gains his QBs trust and gets some chemistry with him, that's even if MVS doesn't improve, which he should in his second year.
Allison put up some good numbers when healthy and I think he's better than people think, and that slot receving role is a star role in this system. So no matter if it's Graham or Allison in that role, they should do well.
I'm tired of the Rodgers physical injury excuse, as that didn't hold him back, his failure in chemistry and trust is what held him back.
