I think some of those fans on the Ravens board have it right: Baltimore doesn't need to start Smith over Boller, what they need to do is start Rick Neuheisel over Brian Billick, and see how that works out for two games.
It'd be a great story to see Troy get some quality PT and rise up, carry this team, and end the season a hero after a fairly miserable season for the Ravens. Unfortunately, there's about a 5% of that happening. This team sucks.
Putting Troy in for four quarters just means Troy will get the tar knocked out of him. The optimists on those boards all talk about how elusive Troy is and how good he has been avoiding the rush and buying time. Bullshit. Opposing teams are rushing four and he's still running for his life because the Ravens O-Line is terrible.
If you stood there for 14 weeks and watched McNair and Boller get obliterated play after play, you'd be elusive too. Run Troy, Run!!!
