Not that they're huge NFL stars, but Southlake Carroll down here in Texas had Chase Daniel at QB (Brees' backup in NO), Garrett Hartley at K (NO Kicker), Adam Ulatoski (OL for HOU) with Greg McElroy as the backup QB (Jets).
I used to live in Southlake so I got to watch all the state champion teams. They could've beaten some small college teams imo.
Scott Chandler (Bills TE) was there too but he graduated in 03 (yr before the players I just mentioned).
