I wouldn't say they are great at jumpshooting. After all, their offense blows and it clearly shows. When their jump shooting gets cold, it gets SUPER cold.
They really need to just keep attacking the paint, which they just refuse to do at times. They did this perfectly against the Blazers and they blew them out of the court. This game... we didn't see much of the exciting Celtics.
Oh, and Paul Pierce really stank it up against both matchups against the Lakers. Artest is definitely in this guy's mind.
