Isn't what the Mavericks are willing to give up to get Jason Kidd too much?

He is a great pointguard, but he is old with little tread left on his tires. He probably has only 1great year left and 1-2good years left in his career. Devin Harris is a potential all-star, Stack and George are still serviceable, but when you add in TWO first round draft picks it becomes way too much! Then if you give up Diop who will have fouls to give against Duncan, Yao, Stoudamiere, etc? They already have a guard that is a 7 or 8 and young. You need a physical presence in the middle when their shots aren't falling. Really how much does Kidd add? Why is everyone so in love with this guy? If he makes everyone around him so much better, how come he can't he make Richard Jefferson and Vince Carter any better? And don't forget the Toni Braxton fiasco! He might fight Dirk over Beyonce.......lol
