Srubiak, is that you? The answer remains the same as last time you tried to put Scraub back in the game.
If you think Schaub is the only reason we are having this season then you must not be watching any games.
The thing is, what other kind of system would Matt prosper in? Maybe he is smart enough to audible at the line, but it'd still be his first year to really do so. He's losing or lost the tools needed to succeed in this system, and/or the system has already been limited to Schaub's declining mobility, arm strength and pocket presence.
