I honestly wasn't that impressed with Freeman as a DC in his sole year in the position here, but I'd take his input in a second over Ash's. Freeman was sandwiched between Lea and Golden, and I thought both were better in the position (Although I like Freeman as HC).
On paper the defense's numbers looked good in '21, but we also faced a lot of inept offenses. Toledo, Purdue, Wisconsin, VT, Navy, Virginia, Stanford, GT were all mediocre to bad offensively that year. I wouldn't even say a 5 win FSU or a 4 win USC were particularly great offenses that year either. Statistically the best offenses we faced during the regular season were Cinci and North Carolina. Those two were strong, but that's as far as I'd go, the others weren't big threats to score or they shouldn't have been. So Freeman looked good that year, but it wasn't hard to look good against poor competition.
I have a feeling he already knows he's Ass, he doesn't need us to tell him
