Beane has assembled a playoff quality roster. He has a championship caliber QB. He has not assembled a championship caliber roster (based on actual results), yet. Until the advance to a super bowl, I can't really change my opinion on roster construction. He is good. Not yet great. I think all of the evidence points to "roster construction" as the sole GM measure. Not draft, not trades, not Free agent signings all separate. Championship rosters have been constructed in all sorts of ways.
