Whatever happen to Harold Miner, Glen Rice and Isaiah Rider who were among the top NBA players before?

It's funny how Miner and Rider were both dubbed as the next MJ while Rice was the back in the days version of Rashard Lewis. Glen Rice had the better overall career while J.R. Rider was plaqued by off the court issues kind of like your back in the days Artest but a more extreme version. Miner never amount to anything more than a dunk specialist similar to Dee Brown while Glen Rice, after 3 All-Star appearances, went to play for championship contending teams (Lakers, Knicks) and accepted the status of a role player in hopes of winning a championship.
