I don't mind the Montross pick, especially since we were able to trade him (and the draft rights to Samaki Walker) for Antoine Walker + a 1st rounder (Ron Mercer).
The pick I hated was the Kedrick Brown selection. First, we took him over a bunch of guys who became NBA contributors (Richard Jefferson, Troy Murphy, Zach Randolph, Brendan Haywood, Gerald Wallace, Sam Dalembert, Tony Parker, Gilbert Arenas, Mehmet Okur).
Second, we had the option of rolling that pick over for up to two seasons. In 2002, Denver ended up with the #5 pick. Guys on the board: Nene, Amare, Caron Butler. If for whatever reason we'd passed on it then (which is doubtful), in 2003 Denver ended up with the #3 pick (Carmelo, Bosh, Wade, etc.)
