Boomer Grigsby has captured the hearts and minds of the Kansas City Chiefs faithful by being a hard worker and enthusiastic player. In fact, Herm Edwards even recently referred to him as a "folk hero", whatever that means.
For all of the effort that Grigsby is putting into earning the starting fullback position, he has put in equal if not more effort into...trampolines. Yes, Boomer Grigsby is a USTA Trampoline and double mini champion, which he earned as a member of the AAU national team. He was also a three-time All-American Trampoline Award champion.
Founded in 1971, the USTA has 6000 members, nine divisions for tumbling, and six divisions for the double-mini and the trampoline. Boomer on his trampoline experience, right after he got drafted:
I'd imagine a lack of fear comes in pretty handy on the trampoline and the football field. Unless you don't fear getting caught in a basketball goal. Then you're in trouble.
