At the moment, it looks like the Randy Gregory story could have a happy outcome. He does still have to meet some uniquely strict requirements as reported by Mike Fisher to actually take the practice field in with the Dallas Cowboys in Oxnard, such as this.
The league admonished Gregory for his occasional behavior with medical people trying to administer drug tests and for his occasional failure to keep the league abreast of his whereabouts. Indeed, sources stress to me that moving forward Gregory will be “strictly required’’ to inform league officials of his whereabouts at all times -- and that not doing so may carry the same weight as a future failed drug test, which will Gregory will likely be banished from the NFL indefinitely.
