*sigh* None of us knows the nature of Josh's substance abuse problems. In addition, Hawkins did NOT say that rehab caused Josh to go downhill. He said he had never seen Gordon work harder than he did under Hue, and then, "Had Josh not had to check into rehab, got suspended, whatever the situation was, he would have been probably the top receiver in the NFL that year. Because he looked incredible, yo. It was amazing to watch. Between him on one side and Terrelle Pryor on the other, I'm like 'Dude, this is gonna get scary for DBs.' "
There is absolutely no implication that things went downhill after or because of rehab.
