Re: Kevin Walter can go sit on the bench..
He could have tried to squeeze it into Martin, but it probably wouldn't have been a completion. I doubt it would have been an INT, but it would have been a contested catch for sure. That safety was on him and watching Schaub the whole play, just waiting to pounce on the ball. On 3rd and 7 with only 4 rushers, it's tough to find an open man, but Schaub made the right call by waiting for someone to get open. A clean pocket made this happen.
