On consecutive trips down the floor, Keon Clark can look like an NBA all-star or a candidate for the league's new developmental loop.

Clark's inconsistency is one of the reasons why the Raptors did not offer to extend his contract last month making him eligible for free agency next summer.

Keon is struggling to stay agressive and play consistantly coming off the bench.  If he fails to pick up his game he may find himself on the short end of the salary stick next year.
