Wall-climbing, upside-down catch continues week of insane catches

The summer of catches continues with this insane run-up-a-wall-backflip-upside-down catch by Mississippi native Nigel Knott. Just watch.

As deep as the four-star defensive back's offer list currently is -- and it includes Alabama, Florida, Florida State, LSU, Mississippi State, Ole Miss, Tennessee, Texas A&M, UCLA and USC just to name a few --  this catch may be Knott's most impressive accomplishment yet.

What wild catch will be conjured up by America's football youth next?
