I think they're just gassed up from tha 2 previous wins. In any round tha Knicks would not beat tha Celtics. They have a good team but I don't think they know how to win yet. Even New York native Stephen A. Smith would tell you that. I don't even think tha Knicks have been past tha 1st round since 99-00.
I won't deny that they have a good team and coach but I will deny them success against tha Celtics. I still don't see tha Knicks getting past them in tha 1st, 2nd, or ECF. With Rondo and Sully out they may think they have a better chance but this team has something to fight for. And they feel they can beat anyone at their best and I would agree. When you have a coach like Doc and players like Pierce and KG that will not allow this team to fold against anyone, they can be hard to beat.
Be careful what you wish for Knick fans. Tha Celtics turn up in tha playoffs and that 3 point line won't save you.
