I honestly don't care who starts at QB. Martinez, Armstrong, RKIII, it doesn't make a difference. They can all be successful, but Beck has to put them in position to succeed.
If Martinez starts, how about using the read option? Martinez went 35 yards on his first designed run of the game today. He may not be 100%, but he's healthy enough to hurt defenses with his legs, and that's the whole point of having him in the game. Yet even in the fourth quarter, when we desperately needed points, we didn't call a single read option.
If you don't think Martinez is healthy enough to run, but you still want to use the QB run game, then you go with Armstrong. But you have to USE THE QB RUN GAME.
If you don't want the QB run game, then you go with RKIII. He's the best passer, hands down.
No matter who you start, the strength of the offense is still the running game, with the offensive line and Ameer Abdullah. That's what you rely on, that's what you go to when you're struggling.
The problem with our offense is not who's at QB. It's that our coaching staff is too stupid to realize the above, or they are too incompetent to put together a cohesive game plan that actually plays to their strengths.
