Except in BBTL, Josh was Exhibit A of the NFL's foolishness. People were calling for the Pats to flip draft picks for him, with the Baylor experience written off as NCAA/ college stupidity.
When people are disciplined under the substance abuse policy, we often don't know the extent of it.
If the NFL were to transition to a regime where weed is acceptable -- for pain mitigation if nothing else --I'd support it.
Meanwhile we know one of several things about players who get caught up in this. They have flunked a stupidity test and they either cannot or are unwilling to stop using. In the former case, they have a substance abuse problem; in the latter, football is not that important. In Josh's case, it appears to be the former.
