i dont see why the Mavs would want DG. he is really not all that good. he shoots a horrible percentage and really only is good for 3's and since the Mavs have added AC Slater, Buckner and Turtle, they really dont need another 3 pt shooter.
and title experiance? please. he was paid to ride the bench and to watch the Kobe and Shaq show. thats about it.
