Devin Harris will step on a flight from Dallas to Newark at 8:05 a.m. Eastern time, Tuesday. He knows, as do the Nets, that his success will determine just how this trade will ultimately be viewed. It won't be the first time he will be replacing a Hall-of-Famer. He succeeded Steve Nash in Dallas. In an interview Monday night, he said he was looking forward to his new team...and new freedom.
