The Rams offense doesn't have the RB they need, the TE they need, the LT or Center they need, or even another dynamic WR that they need. And, I also agree that the offense McVay is trying to run doesn't seem to take into account the lesser talent.
Stafford isn't the issue. He remains a top 10-12 QB that can get hot and be a top 5 QB for several games.
But to think we're going to draft a rookie QB and he's going to be as good in his first year....or even two? That's rainbows and unicorns stuff. Every great once in a while that happens...but it's rare and nothing you can seriously count on. But fans do, and heap enormous pressure on the young guy, and then are disgruntled when the obvious happens.
