People don't need to argue the nfl front office's favorite owner. Which if you don't think after he only got fined $100k and Brady got suspended for being a "repeat offender" that there isn't a clear bias then you are clearly a jests fan. Also how about Suh's suspension for being a repeat offender being overturned because he had gone a season without incident?
But people don't need to argue those because they can argue two other examples that have happened recently.
Shonn Greene cut by the Titans on the first day of mini-camp after he made it known he wouldn't be attending. A player skipping voluntary workouts and being released is prohibited by the CBA. Titans could argue they were gonna release him anyways but they did it on the first day of voluntary workouts and they knew he wasn't coming. If the NFLPA is gonna file a complaint against the Pats for Butler, they too then need to file a complaint against the Titans for cutting Greene on the first day of workouts even if their argument is "we were gonna do it anyway". Verbatim from the CBA " or that a player’s failure to participate in a workout program or classroom instruction will result in the player’s failure to make the Club"
Then you have Dante Fowler getting injured in rookie mini-camp while he was pass rushing against an Offensive Lineman who was blocking, both pass rushing and blocking are prohibited by the CBA in rookie mini-camp. That happened almost 2 months ago, no complaint filed against the Jaguars. There is also clear video evidence of the incident.
