Rookie Of the Year
I think this could be achieved... especially to those teams who play them as starter... Div. III~V teams could be highly motivated on this award. (IMO)
This has been suggested. I think its very doable. They could just run the same algorithm that determines the MVP on all the first year players and you get a ROY. The only issue is in the higher division, there are probably few first year players getting to many minutes, so it might not mean too much.
They could also open it up to any one under 20. In MLB, they ROY can be somebody that actually played in the previous year, assuming he didn't get X number of at bats or pitch Y innings.
