With so many of the top players having chosen to skip the NBA's pre-draft camp, Boston College star Troy Bell is among the top-rated players performing for coaches and personnel people.

``I don't think a lot of players in my position would have come, but I just feel like if you're a guard you have to continually prove yourself,'' Bell said yesterday. ``I know a lot of these guys didn't get . . . to see me play. And I've got nothing to hide. I've been doing it for four years.

``I'm in a good position to really boost myself up. I've never worried about my stock falling because I know I can play this game. I just want to show them some point guard things and keep playing my game.'' . . .
