Yes. If a play is called to a certain gap and the RB doesn't run it to that gap before bouncing it somewhere else, he doesn't play for a Nick Saban coached FB team. Ask Lacey or the 1st string RB at LSU that was SECCG MVP turned 3rd stringer...
Some of the same is true for our pass rush woes. The 3 down linemen MUST stay in their rush lanes. It's ESSENTIAL in Coach Saban's scheme. Aside from the big DE from LSU that went to Dallas, much of the QB pressure in his scheme has always come from blitzes/sending LBs/overloading one side.
The chemistry of the team is off for sure. All in all the OL's had worse games than this one through this season. There's plenty of diversity in the O scheme. Would I like to see a bit more misdirection, absolutely. Other teams aren't slowing down one bit because we're fairly predictable according to formation/down & distance. That being the case it leaves Bama with one option, whip the other team at the point of attack and impose your will. This team doesn't seem to be able to do that, & frankly it's a tall order in this league, however the formula resulted in 14-0 last year!
To answer the OP, no Mc hasn't lost his touch. Other teams simply know what's coming & this offense has lost some identity this year for whatever reason. Chiefly it's been the OL not imposing it's will upon the opposition, but that's just my opinion.
