Ryan Fitzpatrick reminds me a lot of Jake Delhomme...obscure backup gets his chance and makes the most of it. Delhomme's Panthers always had the benefit of an above average O-Line and dominant running game. A bend but don't break defense with a dominant pass rusher. Bill Polian built that expansion team with free agents and has been coaches and had immediate success but left it in Cap Hell. It took a few years but Jerry Richardson and Marty Hurney brought in the right coach and stayed committed to him through the thin years while building the team back up through the draft. They got to the Super Bowl and almost won but have never quite been the same...one big reason, in my opinion, is they stayed committed to Delhomme for too long and ignored the quarterback position in the draft.
Bottom line...be realistic with what you have in Fitzpatrick - celebrate the successes and endure the failures, have faith in the coaching staff and Buddy Nix, and be patient that the right draft room decisions get made in the future. Buddy Nix is the right guy but understand who is in that room when the picks are made. Todd Collins was picked largely on Jim Shofner's nod, for example...a lot goes in to who gets picked...not the least of which whether or not the guy will sign and will stay beyond his rookie deal. My vote, trade down, get a franchise left tackle and use the rest of the draft on defense.
