There’s talk in league circles of at least one NFL team that has imposed on at least one free agent signee a private, non-sanctioned drug test.

We’ve been told of at least one situation in which a player tested positive, and the team then used the positive test to leverage the player into taking less money.

It’s blatantly inappropriate for any team to use its own drug-testing procedures.  But players who want jobs might not be inclined to say anything about it, and thus the practice will go undetected — and unremedied.
