This is the first mock draft list for 2007 I have seen with Jamal Tatum. This site, just updated yesterday, projects him to go 55th overall, late in the 2nd round to Milwaukee. Sites like this have been fairly accurate in predicting the top 10-15 draft picks, but after that they have been very inaccurate, especially near the end of the 2nd round. Tatum boosted his stock with his fine shooting in SIU's games in the NCAA. He will likley get invited to a couple of the predraft camps where he will get more chances to impress NBA scouts.
