The neat thing about the internet is that when people lie shamelessly, counting on no one to call them out for it, all it takes to prove such is a couple minutes of research.
FAU went 3-9 the year before Kiffin got there. In his first season, they went 11-3 and won the conference. They went 5-7 his second season, and then in his third and final season they went 10-3 and won the conference again.
No amount of truth distortion can ever make leaving a team at 10-3 "worse" than 3-9. Stop lying.
Josh Heupel went 12-1 his first season at UCF, after they had gone undefeated the previous season under Scott Frost. His second season they went 10-3, and his third season they went 6-4. So Heupel demonstrably, inarguably left UCF worse than he found them. Stop lying.
Come back on here in three years, or even two, and we'll see how much of a loser Kiffin is. Somehow I have a feeling you'll be nowhere to be found when this topic is broached again at that juncture.
