Sani is right. As mediocre as they SEEM, statistically speaking they are above average. They have just been mediocre lately, much like Syracuse. They're a Top 20 All Time program.

By your own source (actual relevant info
here) they are 24th in Win Percentage.
Behind Alabama, Tennessee, Georgia, LSU, Auburn, and Florida in the SEC. In other words, bottom half. Three spots above Arkansas. Hardly great.
Others above them in that list: Miami-Ohio, Washington, Arizona State, Central Michigan, Colorado...
Just sayin', they've been Texas & Oklahoma's doormat for as long as I can remember.
Haven't had less than 4 losses since 1994 (2 years they had three, but the record shows they actually had at least one win vacated in both of those years).
I think they water down the SEC (in football at least) more than they strengthen it.
