Nothing ever is easy. You said it was too much to expect a rookie WR to contribute. I point out they do and they can. What is more likely to happen though a rookie WR comes in and contributes or Tutu contributes in a meaningful way for a playoff team, one that wouldn't use him in the playoffs last year btw.
We're all Rams fans we all want this to be a good signing and for him to blow it up and make anybody doubting this signing look up a recipe for crow. But he's done absolutely nothing to give us reason to believe that he can be a #2 WR on a playoff team, since he's been on this playoff team for 4 years and hasn't done anything yet beyond a couple average games when there were no other options. I get it I really do, I just see nothing to hold out hope but as always I've been wrong before I'll be wrong again and I'll admit it.
