Not a good sign for the Mavs. I don't think they are one of the teams to beat anyway. If you look at Rondo's stats since he was traded, his assists and rebounds are way down and his shooting has also been down this year. He has been less than average with Dallas. Less than average at the point guard position will get you smoked in the postseason, in a conference that features the likes of Westbrook, Lilliard, Curry, and Parker at PG. Dallas is meat in the playoffs.
