Sorry, the officials were the difference in that game.
As for Mac - you cannot "scheme" a QB who plays well from the pocket if he is also coached well. You guys worry about defensive schemes because of what happened to Tua. Well, that happened because you were running a gimmick offense and you did not have a real QB coach. You are not running that kind of offense anymore.
One more point that needs to be brought up - Mac is smarter than Tua. Not disrespecting Tua's talent, but everyone in Alabama's program talks about how smart Mac is, and they always have. So, Mac does not have Tua's ability, but he is very well coached and he is very smart - and he also has above average arm talent.
You will take a step backward with Mac, but not as large a step as many of you fear, and certainly not the kind of step that should have you worrying about defensive "schemes" being his downfall.
