There is a newest Chicago Bull, and his name is Bobby Portis, selecting him with pick 22 in the 2015 NBA draft. Portis is a 6'11" PF from Arkansas, a 20 year-old Sophomore.
It's tough to assess 'fit' with picks this late in the first round, as typically these players aren't going to be great enough to push established rotation players out anyway. But that said, with the Bulls lack of flexibility this coming offseason it is a bit surprising that the Bulls didn't go with a guard here. But that could mean that adding to the Bulls very deep frontcourt tonight could actually mean a trade of one of those four established players soon.
