If you've been in the league 14 years, played for near 10 years and only have one play off victory, with one of the top 5 best receivers to ever play, a HOF TE, then you suck. He was a star in the regular season, and a JAG in the play offs. You can't be considered great when you falter in the play offs.
And this is where pedigree comes in. Big time, big school QBs. There's a reason they play there, and if they have success, that's even better. You need a BIG SCHOOL QB, with a nice size and a big arm, with the smarts of a natural QB. And most of all, you need a coach he will not dumb him down.
