One of the biggest things that is always underrated with football is team unity, more specifically unity amongst the different positions on the team.
The offensive line unit is not only very young and very good, but it is one of the closest knit groups I've seen at TN. It has also occurred at every other position on the field (maybe with exception of QB, because I don't know personally the relationship between those guys). The RBs are friends, the WRs are friends, the LBs (in particular Maggitt and Johnson) are friends, the DBs are friends. One of the saddest things I've seen on the Hill was the fighting amongst themselves. It was a huge problem at the end of the Fulmer era, it was still somewhat of a problem in the Kiffin era, but now Dooley seems to have united the team.
I know this is a bit OT, but I thought it was an interesting thing to point out.
