And since I have not seem many ISU players even receive that punishment, my assumption is not that ISU players don't do drugs but that ISU is making sure that players aren't failing drug tests. So is that really better?
Assume whatever you want. Neither of us have any idea what's going on. ISU's policy does appear stricter than KU's in this instance at least. Greene would have been permanently suspended after strike three at ISU. There isn't even a policy for "Fourth Offense" at ISU because you're probably gone after getting busted thrice here.
