On Sunday the inconsistent Boston Celtics  bench will be tested by a newly improved New York Knicks  second unit. The trade for Al Harrington  gives the Knicks the luxury of having a starter come off the bench. Celtics head coach Doc Rivers  said the Knicks reserves were already deep with guard Nate Robinson  and the addition of Harrington gives the second unit even more weapons.
‘[Harrington] can go from the post to the three-point line and the four spot, and it makes it a very difficult cover,’ Rivers said after Saturday’s practice. ‘They also put him at the three at times which makes them a more physical team. So I guess he’s giving them versatility. When you look at with (Zach) Randolph , he was a post guy. There was no doubt about that. He was going to go to the post, so I think that’s where they changed.”
