Think of it this way. Would you rather have 23 year old Wiseman or 24 year old Scheierman? Who do you think has more upside?
Last season in DET, 63 games, 17.1 minutes, about 7 points, 5 rebs, 0.6 blocks. That is a pretty good floor for a player you can think of as a late round draft pick. Will Scheierman come even close to that production next season?
I don't know what happened to Wiseman. I know he was injured for a whole season. But I remember seeing him play his rookie season on GSW and he looked pretty good to me. I have not seen him play much since then.
