Not just our team, bur every team needs a solid bench. What is a solid bench? A solid bench includes three guys who can score and two other guys who are determined to play defense. To me, you need a good, offensibly versital, back-up point guard, you need a swingman who can score and shut down the opposing stars and you need a veteran big-man who can hit mid-range shots and score in the post. For example:
(Talking about the bench)
PG: Kirk Hinrich, Anthony Johnson, Anthony Carter
SG: Ime Udoka, Dahntay Jones
SF: Grant Hill, Shawn Marion, Ronald Murray, Matt Barnes
PF: Antonio McDyess, Rasheed Wallace, Drew Gooden
C : Joel Pryzbilla, Kwame Brown
*These are the three key guys who can get it done offensibly
These are the two other guys who are there to play defense and may fall out of the rotation in the playoffs
So, I say we (the Celtics) have to try to get the Anthonys (Johnson aand Carter) first, and if that doesn't happen, we have to re-consider Marbury. Then we should try to get Hill or Barnes (I think we shouldn't take Marion to the bench as he wasn't happy being the third guy in Phoenix), we could get them without the MLE. So, after having the PG and the SF we gotta get a big. I dear to say that McDyess doesn't want to play for Boston, so i jump to Rasheed. He'd be a great back-up with his scoring ability and I say hi should be the number one guy for as to get (assuming that he'd "settle" to the MLE). If he doesn't ("settle"), we can always try Drew Gooden.
That gives us three important pieces to our bench, then we should focus to the role-players.
