they are simply tests that had negative results, lots of things can throw them off.
since only a few were allowed to respond on dolphins thread and theres still his thread that suggests Seahawk players have cheated I'd like to say this..
lets test everyone on the Dolphins squad and see what we come up with?
what do ya say about that?
