Harvey was an empty vessel.
In fairness, that draft was a desert after him. A remarkable absence of talent.
Weis was drafted by Affirmative Ed Tapscott, a bum's bum, who was put off by how street Ron Artest was. Also, he was on his way out the door, so not beyond the realm of reason that he fucked the Knicks as a parting gift.
Of course, poor Weis...douche nozzle Van Gundy punked and demeaned him, and they were experimenting with new rules & new refs in summer league, so Weis absorbed an orgy of foul calls, had what little confidence he possessed beaten out of him, and the rest is history.
