Hopefully, Horford's performance will be in the same ballpark as Parish, McHale, Bird, Walton, KG and Pierce. I won't include Shaq, because he never really played in Boston. Jefferson didn't play long enough here. I would prefer to forget the Gaston era--the worst in Celtics history.
It won't be that easy for Al, because he doesn't have the same quality of bigs around him as the others. We'll see how much of a help Johnson is. I'm not big on the rest.
