They do have more confidence with Masson. Don't reference a game for which McGuire played last year and only passed well on the last drive. Also, he looked shaky at best in the spring which is why he is not the starter right now. It's always vogue to holler for the backup when your starter struggles but Masson is ahead of McGuire right now...Period. He definitely gave us a boost but I think you'd see the same results if he was starting to be honest. Also, you forget that Masson did NOT turn the ball over and he has consistently been plagued by his receivers dropping passes which also kills momentum.
If the coaches were so confident in Brad throwing the ball, why did they take him out when it was time to move the ball in the air and on the final drive?
