It is quite the message sent by Knicks owner James Dolan about what he thinks of his roster when the general manager who built it is fired with a 0-0 record. Preseason record. The Team that Glen Grunwald Built and Dolan apparently doesn’t like opens training camp with meetings Monday and the first practice Tuesday. A new president/GM Steve Mills will address the media Monday regarding a team he had nothing to do with forming amid a surreal atmosphere only Dolan’s Knicks can create. The 2013-14 Knicks still could be good but Dolan must believe the consensus they’ve fallen to fifth-best in the East — behind Miami Derrick Rose’s Bulls the improved Pacers and the reported juggernaut in Brooklyn. But if Amar’e Stoudemire’s knees hold up Andrea Bargnani lives up to his lottery potential Carmelo Anthony duplicates last season’s gem season and J.R. Smith and Metta World Peace don’t implode the Knicks could be back to where they were last season — Atlantic Division champions and the East’s second seed. If not Mike Woodson likely is gone after the season. Dolan still can’t get over Woodson’s so-so performance in the second-round crushing vs. Donnie Walsh’s Pacers. “We caught them by surprise in the first game’’ Walsh told The Post. “In the sixth game one play turned the whole series — the block of on Carmelo by [Roy] Hibbert so we got the series.’’
