Apparently, the Mavericks didn't they think could live without a 39-year old point guard who shot 36% from the floor and was no longer useful defensively.
It would be one thing if Kidd's "veteran leadership" and "locker room experience" could attract free agents like Williams and help make Dallas an NBA destination, but if the Mavericks are just paying him for his on-court value, anything more than a one-year veteran's minimum is a drastic overpay.
Kidd is a bigger Derek Fisher: he can't penetrate into the lane and he can't defend anyone. At this point, I'd rather Rodrigue Beaubois and Delonte West get minutes at the 1. Kidd should only be back in Dallas in an advisory role like the one he played on the 2008 Olympic Team.
