Exactly Brohm was getting the ball out faster than Willy, Marve runs better than Willy and and cotton found his holes in party because Marve helped open **** up and in part because he's just plain better than Grigsby. O-line wasn't really any different.
Exactly, with Marve's mobility the D couldn't focus on a single point of attack so that opened up everything for Cotton. The O-line was never that bad, it was the protection they were trying to provide to the pocket on every play that caused most of the breakdowns. Sad that Marcel couldn't figure this out earlier.
