While none of them wrestled, we have some Kansas boys that excelled in football while being small in stature. Gayle Sayers (this is a stretch because guys weren't as big back in the day), Steve Tasker (hall of fame nominee and noted as the greatest special teamer in NFL history), and Barry Sanders.
One that excelled in wrestling and football is Paola's Brian Shay (once held the NCAA record for most combined yards from scrimmage). This took some research but, his most recent playing height and weight was 5'8" 213 lbs. He was a state champ at 160 and was listed on the 1995 Wrestling USA all america team Honorable Mention. He also won a state title at 189, but I'm guessing that he was a pretty good football player at 160. This one is a stretch, but I would call him a "little guy."
