I'd call Tito the most "mediocre" I mean who did he beat really...Wandy and Vitor. He couldn't get past Frank, Randy was the HW champion, most of the Pride guys would have killed him, and he ducked Chuck for half of his reign. Forrest was I believe an underdog in most of his UFC fights and he won the title. Forrest was the legitimate undisputed light heavyweight champion, Tito wasn't.
Now where the guy is, he's recovering from a major injury(MCL) and they will likely match him up with Wanderlei or Chael.
Tito was a dominant champ in his time. I completely disagree with you. Sure he's annoying an went WAY downhill after his reign, but he was legitimately the best guy at the time. You can't blame him for who was r was not in UFC at he time.
