You would have to break it down into at least O and D.How well did they do through your eyes this regular season?
O is pretty obviously an A+++++++++++++++. With the talent UT has they have no business being the best O in the country. The staff has done an amazing job. The OL coach seldom gets mentioned but he may have done the best job of any of them.
D to me is also pretty obvious. Something D- or below. Banks gets a big fat F. It is a popular thing apparently to blame assistants. Assistants run drills. They teach technique. They support players and try to motivate them. You can nitpick those things but there isn't a common thread running through the season for anything that leads back to an assistant.
UT doesn't have ideal talent. However you will not convince me that they don't have more talent than a whole bunch of teams ranked ahead of them both in the SEC and nationally. UT is #128 in pass D. I'm not buying that they are so less talented than Mizzou or MSU or UK or Iowa or Iowa State or Northwestern or Syracuse....
The things that have hurt UT most and consistently are gameplanning/scheming and play calling. The things that have hurt UT the most and most consistently point back to the DC.
