Two games that come to mind. 1991, in the kickoff classic. We tied eventual National Champion Colorado 31-31. After trailing 31-17, late in the 4th, our o-line took over the game, and bullied its way to a tie, and were seconds away from a winning FG attempt. If only Chuck Webb had gotten out of bounds, earlier. But, he nearly took it to the house.
Also, 1992, vs 8-1 #5 Notre Dame, at South Bend. After trailing 31-7, in the 2nd quarter, Floyd Miley picked up a blocked FG attempt(Blocked by Darryl Hardy #87), and ran it back for six. Tennessee rallied, in workman like fashion, in the second half, to win 35-34, after the attempted winning FG glanced off of Jeremy Lincoln's buttock, as he flew by the holder.
One thing that stands out to me, in both games, our o-line enforced its will, late in the game. Something I look forward to witnessing again, someday. Phillip Fulmer was the OC in both games. He knew how to build an offense around the guys in the trenches.
