All things equal, Smith is better than Cassel. But it's like going from a Lean Pocket to a Hot Pocket...we're still starving and it's very unfulfulling.
If Smith can come here and be efficient, like Cassel was in 2010, and he has been that last couple of years, they'll win 7-10 games.
If Geno Smith goes on to be a stud though, this is pretty unforgivable.
