True, but if I recall he moved Dyess to the starting role before the end of the season. We are approaching that stage now and there doesn't seem to be much indication for this. If Blair can keep occasionally having those big 20 point scoring nights which are important for us, I can see him sticking in the lineup.
Duncan looks much better this year than he did last year. Also, last year we had Parker struggling in the playoffs, and we had the pussy RJ in our lineup. So it was normal that Dyess was needed for defense or otherwise we would have been much worse.
Now we have Parker rolling on offense and defense, whoever starts at SG will be bringing energy and defense as well, and Leonard is a very good defender and keeps improving. Technically, Blair would be the only weak defender in our starting lineup this season. In comparison to last year when neither Parker or Manu were rolling and RJ still couldn't defend if his life depended on it. I honestly would hope Blair still gets some significant minutes in the playoffs while Mr. Bonner "I cant make a shot in the playoffs" is dropped to a much lesser role. The main bigs would be Duncan, Diaw, and Splitter while Blair gets minutes depending on how he starts and Bonner might get minutes depending on the matchups.
