Jarron (a 24th pick) had a 10-year career with 0.88 winshares/48 (Basketball Reference), and Ostertag (a 28th pick) had an 11-year career with 1.10 winshares/48. If we get anything similar to this out of Bradley, it will be a major win.
Jarron Collins was not pick 24th. I think he was picked somewhere in the 40's. It might have been the 42th pick. I agree with your point though.
