I am not sure if this has been posted before but I stumbled upon it today.
http://dberri.wordpress.com/2008/08/25/the-miles-file/I think the analysis is fair. Berri picks the Lakers due to Bynum coming back.
What I think though is that if Miles can play to a level of an average SF, that will be fine. That may be a big if though. His knee may be so bad that he can only play once a week or something. If he can't, we might still be OK but we would need a couple other "ifs" to come through.
I also think that any historical analysis to project the contribution of Paddy'O is irrelavent. I trust the judgment of Ainge and the scouts enough to have seen enough in him that he can be an alright back-up center, better in fact than Pollard and PJ (yes, PJ, I don't think PJ was all that great last year). O'Bryant's contribution is another "if" though.
Then we have the rookies. It is interesting that Powe and BBD actually contributed in their rookie years and combined last year pretty well. It may turn out that Giddens and Walker form a similar kind of 1-2 punch to work against different kinds of match-ups and collectively, make a needed contribution (assuming Miles bombs out). Enen then, there is still no room on the 12 man roster for Pruitt which would be a shame.
All this considered, I can't see the Celtics being the favorite to win the championship but I think they will be right in the hunt with a realistic shot.
