This is a tired argument as long as it is NFL policy. What about players in CO, WA and DC where ii is not a crime? It is still a rule and so far the only one speaking out publicly that it should not be a rule is Booger.
The problem is while the majority of Americans think it should be at least decriminalized, the feds are threatening the states where is it legal with enforcement of the federal law......again The NFL is not going against DC and lift the ban on weed as an infraction.
If I were the Commish, I would have one simple rule. If you ain't in jail, suit up. I wouldn't test them for anything including PED's, they want their brains and testicles to shrink at the same rate, have at it.
