I think that's because we haven't had many good receivers in the last 10 years.
2011- Posey. Eh.
2010- Dane. He didn't drop passes.
2009- Robiskie and Hartline. Robiskie dropped his fair share of passes, and really wasn't/isn't that good. Hartline was good, didn't drop passes.
2007- Roy Hall, Gonzo, Ginn. Ginn was never a great pass catcher, just incredible elusiveness. Gonzo was a guy you could count on, didn't really have issues with drops. Roy Hall...eh.
2004- Drew Carter, Mike Jenkins. Carter wasn't really special or anything. Jenkins was good/great.
2001- Ken-Yon Rambo, Reggie Germany. Neither were that good.
So, in 10 years we had 4-6 solid pass catchers. I don't care who your coach is, gotta have someone to throw to.
