Regardless of how good Delonte is at shooting compared to other sg's in the league, we are talking about him getting what would be in most cases a fairly open jumper in the situation where we would be passing to Delonte out of a double-team.
Unless you are trying to tell me that we would just go to Delonte West from the get-go and not wait around to see whether Paul Pierce or Ray would be double teamed first? I'm sure that our offense would be able to cope with special types of perimeter defense, whether it be setting screens or using the pick and roll, Rondo driving into the lane and then either going for a lay-up or feeding someone in the paint, kicking it out to an open shooter, etc.
