Here's another opinion of the situation...
Why Mike Shanahan may start Grossman over Beck
Grossman may have thrown a ton of INT's but I also have seen a ton of balls that should have been caught or the receiver should have made and attempt to go up after the ball and or fight for it. Our receivers are not the type to go up and challenge for a ball in the air. Heck our receivers are not the types to be told the ball will be in the center of the field on the 10 yard line go get it. I wish we did have those types of WR's but we don't. Which is why I can see Beck throwing just as many INT's as Grossman because although Beck has a stronger arm and will throw the ball farther.... I can see where the receiver's won't go after the ball and the other teams Safeties or CB's will.
