I think he's a good defensive coach and schemer for sure. With regard to that offensive plan yesterday, though, it ONLY works against a team with a QB as shaky as Mariota. TN's offense isn't good. Both the offensive gameplan and the overall scheme were high-school level in their sophistication, which ironically was just what the doctor ordered given the opponent. But they showed no signs yesterday of being able to run a complex offense -- the sort you need when facing the good teams who are bound to put up 20+ points. Baby steps, I know, but I'd like to see a bit more sophistication going forward because Jeff Fisher is no model to follow in today's NFL.
