For your team, who was the most heartbreaking player?

The guy who looked great in the draft, came out and was an absolute failure. Maybe you bought his jersey after draft day for 95 bucks online, got his autograph and framed it. Okay, well I despise Jerome Moiso, a former UCLA standout and NBA failure after the Celtics drafted him in the first round. Who is your teams equivalent? The ultimate failure who u thought was the next NBA great.
