I still think rookie of the year is still a good idea. Out of all the teams in the leagues, at least two of those teams are playing rookies especially if they are MVP and up.
what did it have to do with potential, especially for rookies there are nearly no differences betwenn the difference potentials.
And at least for my league, we don't have rookies with significant minutes in league, if we use then in league just in forfeiting situtions because of a hard cup game.
