Their D is not good, but either is ours. They give up 1 more point per game despite playing much faster than we do.
On an efficiency basis their D ranks slightly better than ours.
Offense though is insane. #2 efficiency offense in the country and they lead the country in the following categories
PPG, total offense, total first downs, 3rd down conversion rate (59%), three and outs (6 in 9 games).
With a healthy Haynes and King we have a very good offense, their offense is just a different level.
Their special teams also rate much more highly then ours.
Given all that, we can still win this game, but GT must have a +2/3 TO margin, must be able to control the clock (that doesn't mean it has to run all the time, you can control the clock through passing as well), and must execute cleanly in all 3 phases.
Assuming we have King and Haynes back I think we keep it close but Miami does what it does and pulls away in the fourth quarter.
