Fitzpatrick may turn in to a hero, or he may turn in to someone who's on the brink of being out of the league.
So my advice to you, don't discount any potential scenario just yet. Fitzpatrick is only 27, doesn't have all that many starts to his name for the amount of years he's been in the league, and has showed major poise against good defenses on an extremely bad team.
I'm not saying he's going to be the next Elway, Favre or Young, but each of those three struggled in their initial games in the NFL. So don't dismiss any notion until the writing is on the wall.
