I'd say the worst evaluators of talent is VN as a whole. I'm pretty sure every commit from the last decade has had a thread about them filled with "BOOM" posts, gifs and memes. A few years later (after ANOTHER coaching change) we see posts like, "Coach (Dooley, Jones, or Pruitt) can't expect to win with the players that crappy coach (Kiffin, Dooley, or Jones) left him....the same players with BOOMs.
I think each coach wants a certain "style" of player to fit their needs. The question becomes will that "style" win in the SEC? I think Pruitt saw UT as too small and too slow to compete with UGA, UF, and Bama on an annual basis even though there are/were some talented players left by the previous staff....just not enough to compete with the top teams in the SEC. That seems to be changing, no matter where the rankings land.
