You guys do realize he lost 3 MAJOR pieces of their rotation? Not to mention pretty much losing Jason Kidd, the guy who ran that team. Going from 8 and 8 to 4 and 5 on 28% shooting.
With an almost 39 year old Kidd, Vince Carter, and especially with no JJ Barea, Dirk's pick and roll/pop game has taken a huge hit.
Also, everybody knows that teams just happen to play better vs. the current champs.
Dirk and Terry are two of the best guys you can ask for in a close game, all they need is some actual help to get the team through the first 3 quarters.
