I'd prefer not to say the name of the high school, since it's in a small town and people might be able to find me there still...
Travis Knight - NBA player
*Played for UConn, then was drafted by the Chicago Bulls and then was renounced, so picked up by the Lakers. Has played for the Lakers, Celtics, and Knicks, but it looks like he hasn't played since the 2002-2003 season.
(I still remember when he came to the high school my senior year and was presented a key to the town - or was it the school???
)
