Easy, first one that comes to mind is DeShea Townsend. Teague is another. Pep has done a good job, Moorehead is staring to make his waves, Griffin has shown his talent, and Fernando Bryant has done well.
Off the 1992 team, George Teague and Antonio Langham both were significant NFL players, and Fernando Bryant has been around a good while. There are several others, but none that had the upside of McCants.
McCants had freakish physical ability, but was not sound on technique, so he fizzled in the NFL.
