He was a good bit better then solid this year. He was actually quite good considering the circumstances.
Sure, but let's not get carried away. He had two games against the putrid Jets, one against the equally putrid Jaguars - and one against the 49ers playing their 4th string guys or whatever. That's 4 of the 7 games he started this season. The 3 other games were losses (Patriots, Bills, Seahawks) in which he threw 0 touchdowns to 5 interceptions combined in two of them, only showing any kind of life in the Bills game. I will say that his "closing" effort in the Raiders game was great.
Like I said, I love Fitz. He seems like a really great guy, I love the energy and joy he shows and he's possibly the best backup quarterback around. But nothing I've seen this season (or the rest of his career) would want me to install him as the starter. With Fitz, we'd go on a roller coaster 8-8 season, guaranteed. He'd look awesome in blowout wins against scrubs, fail horribly against really good teams, and oscillate between FitzMagick and FitzTragick against the average teams.
