Aside from ESPN, which has a draft writer who loves Melvin Frazier and still has him going in the first round, I'm seeing multiple mock drafts that do not have him going at all, even in the second round. A couple still have him going high in the second round.
Other than his decision not to hire an agent, I don't know what Frazier's thoughts are, but he would be taking a risk to stay in the draft. That risk might pay off, but it will be interesting to see what materializes in the next month.
Tulane could be pretty good next year if Frazier returned, although still light on post players.
