Oh, come on, Ed. Surely you don't believe this. The people who vote players into the Hall of Fame are students of the game. They know that Wallace didn't like playing in the paint, despite his ability to dominate there, and that he loved to stand around and jack up 3-pointers. They also know about his crucial defensive mistake against Horry (was it Horry?) that may have cost the Pistons a championship. And they're certainly going to remember his setting the record for technical fouls 2 years in a row, and getting kicked out of games, and attacking a referee after a game, and refusing to lift weights with the rest of the Blazer team, and throwing the towel in Sabonis' face, etc., etc. Wallace has been a petulant, spoiled brat for his whole career, and that is a fact. Those kinds of players don't get into the Hall of Fame, and neither will Wallace.
That said, however, I actually think he might be a good addition for Cleveland. He never wanted to be "the man" anywhere he played, and in Cleveland he wouldn't have to be. They'd probably let him stand around and jack up 3-pointers to his heart's content, which he is fairly good at, and that might be just enough to put the Cavs over the top next year.
