And before the Celtics even get to think heavily about Marbury, you may be seeing more of Gabe Pruitt. In brief meaningful opportunities (read: not garbage time), Pruitt has shown he can score. And his defense has caught the eye of those who took his shooting for granted.

If the Celts want to expect anything from the second-year guy later on this season, then they’ll have to start working him in soon. Even though Marbury is ahead of Pruitt on the food chain - Celtic types were impressed with what they saw of him in the preseason - how well Pruitt does if given a chance soon could have an impact on how much they’re willing to promise a newcomer.

Couldn't have said it any better.
