I think the record for a season at Tennessee is something like 50, set in the early 2000s. Over a 12 game schedule, that works out to 4.2 per game. That year, we probably averaged more against bad teams (if I had to guess), but I doubt we piled up 10 in any one game. We also had much better DL and LB talent back then.
All this considered, I'd think 4+ would be a solid afternoon against AP. Getting to about 25 sacks or more on the year in total would be solid work as well, given the talent we have and the schedule we're playing.
