Thoughts on the Playoffs

My first thought is about Stephon Marbury, the second about Mikki Moore.  I read on Wages of Win that Mikki Moore was not a very good player; he simply played more minutes and his productivity was up because of it.  

Also, Stephon Marbury came out of a one and a half year hiatus to play for the Celtics and is not nearly as productive as he was.  And I don't think that should be surprising.  If you don't play NBA level basketball, or any level basketball, for 18 months, you can't come back and be an impact player as a guard.  Maybe a big man could do it, but not a small player who relies on quickness, speed, and shooting touch/shooting confidence.  

Are there counter examples?  BR article, perhaps?
