I don't like Eddie House playing as an off guard. I think it puts too much pressure on the team defensively, and on the backboards. I much prefer him as the point guard.
And I don't like him as a pg. Our offensive sets break down when he's running the team. So maybe he is the problem. Does his shooting out weigh all of his shortcomings?
I think his defensive/rebounding limitations as an off guard far outweigh his offensive negatives as a point guard.
I don't think Eddie gets enough credit for his all-round play as a point guard, and I do not think his lack of playmaking/floor general skills are costly to the Celtics. I don't think those limitations come anywhere close to outweighing his positive contributions at the point. I'm quite happy with Eddie as the C's backup point guard, I think he does a very good job.
I also think his shooting is extremely valuable to the Celtics because he's the only player outside of the Big Three who is a very good shooter. TA is not and neither or the two backup big men, nor Rondo, nor Perk. Marbury is a solid shooter but not a very good one, it'll be interesting to see how important that downgrade is over the next few weeks ... maybe Marbury adds enough elsewhere to make up for it, but maybe not. I think we'll have to wait and see.
If Marbury is the best option for the team at the point guard, then yes, I don't want to see Eddie in the backcourt with him. I want a legitimate wing if it's at all possible. The rookies need an opportunity, and TA needs an opportunity once he returns to see where his conditioning/form is. Only if those players are utterly incapable of taking the role do I want Eddie as the team's off guard in the playoffs.
