He's a safe pick, start with that.
Comb through the data, videos and critiques surrounding UCLA's T.J. Leaf, and it doesn't seem possible he'll ever slip into the "bust" zone. His shooting touch, versatility, athleticism and basketball pedigree should make him a solid NBA player, at least.
The question for the Pacers, who took the 20-year-old Leaf with the 18th selection in Thursday's NBA draft, is whether he can rise beyond "solid" to the atmosphere of "steal," and that answer won't come for a few years.
The Pacers took another UCLA big man, 18-year-old Ike Anigbogu, with the 47th overall pick, and then sent cash to New Orleans to select point guard Edmond Sumner with the 52nd pick.
