shown data to demonstrate more/less drops, more/less YAC, more/less penalties, more/less blocking assists. ZERO metrics. Which is not surprising, because most CB'ers are ALL about perception, narrative, and opinion.
Cahoon has been a solid WR coach. The problems with BYU's football team last year cannot be pinned on Cahoon.
I saw culture, discipline, strength & conditioning (with the resulting injuries), team division, and scheme as the problem. ALL OF THAT goes to the HC.
