Completely agree. McDaniel is a good offensive strategist, but I don't think he can effectively motivate his players, especially when games are need late in the season. Much of the reason, they often collapse.
The other issue with McDaniel is...he has a Tua problem. He has to design plays that protect Tua to the maximum extent possible. I believe the reason Tua got hurt against Hamlin, is he got brave. He went a full year without an injury, and then bam. It'll happen again. It's just a matter of time.
