Who is Matt Schaub?

He really doesn't seem to get talked about very much, basically having spent his career as "That guy who throws to Andre Johnson" on losing teams. Then the Texans made the playoffs last year, and even won a game...without him. He's frequently injured, but obviously has a couple big seasons under his belt - led the league in passing yards in 2009, and did it awfully quietly.

Imagine a lot of it has to do with the fact that the Texans are a new franchise and don't have a lot of "die-hard" fans yet to pump up their players, but they're an up-and-coming team now, and what prompted this thread was seeing on NFL.com that the Texans were being talked about a contender for AFC Champions with Matt Schaub back. So for any Texans fans, or at least fans of teams playing in the AFC South, what's this guy all about? I really don't know anything about him other than his stats - just never watch any Texans games.
