Well I bothered to go look him up. He played at low level D1 college and played #6 singles and also played doubles. It looks like he only played one year. He is in his mid 20s. Apparently the league coordinator is aware of his background and says he is "fine to play" according to people I talked to- lol.
The league coordinator is wrong then when the guidelines clearly state D1 = 5.5. Basically the League Coordinator is condoning cheating.
