Today the NFL notified teams that Jabrill Peppers from the University of Michigan had a diluted sample on his combine drug test. This comes on the heels of reports that Reuben Foster of Alabama was guilty of the same infraction.
Now although treated the same, a diluted sample is not the same as a failed test. Diluted can translate to something as simple as the player being too hydrated for the sample to be tested. With players trying to perform to their utmost abilities at the combine, it would make sense for them to want to stay hydrated.
