I appreciate all of the input. Son has offers to play his grad year in both the SEC and ACC. One of the ACC schools offers a more valuable/prestigious degree that could have value over the 40 year horizon. What I was seeking was to understand IF there was any appreciable difference in terms of scouts/draft by conference. It does not appear that the collective wisdom here believes that there is a difference, which is helpful to understand.
He will make his own decision - his mom and I were seeking context in case he asks for advice
