B.S.
Define Talent - Parker, Manu, Duncan have come through repeatedly on the largest stage and Hill, Jefferson, Dice, Blair and others have just as much "talent" as the vastly over-rated Marion, Caron, Terry and others. Each of the Mavs beyond Dirk are often inconsistent.
Dirk is a great all time talent and Kidd is one of the best PG ever (but has limitations these days, in particular speed kills him) but is pure BS that Dallas has a more talented squad.
At the worst it is a toss up but give me Spurs healthy any time over the Mavs.
