From a 2008 ESPN article about physical specimens:

Allen Bailey, Miami, DE: A sophomore, Bailey might be the No. 1 on this list next year. The powerhouse Georgia product is one of those rare talents with a background made for legends. Like the time he once killed an alligator with a shovel. Bailey, who wowed Miami coaches with his smooth transition from linebacker to defensive end, was almost as impressive in Miami's spring workouts where he weighed in at 286 pounds with 8 percent body fat and vertical jumped 38.5 inches and power cleaned 375 pounds -- numbers that surely are adding to the Bailey folklore around Coral Gables.

"He's about as freakish as they come," Miami strength coach Andreu Swasey says. "He's like a big Willis McGahee. At almost 290 pounds, the guy is sculpted like a Greek god. I expect him to break a lot of records around here before he leaves. He will be a 41 or 42-inch vertical jump guy, run in the 4.5s or low 4.6 and clean 400."
