They'll lead with a citation of "irreparable harm" being done to the league if Elliott is permitted to continually play, although NFLPA attorney Harold Kessler has already shredded that argument -- stating the NFL can not now claim irreparable harm after themselves allowing Elliott the play in Week 1 vs. the New York Giants.
In other words, it can't be suddenly deemed a problem only days after the league stood in front of Mazzant and professed it wasn't.
Kessler went on to explain in his latest filing that the league stands to feel no sting by a potentially delayed suspension, whereas Elliott and the Cowboys would most definitely suffer a monumental blow. While it's not plausible the NFL will win the appeal, it is possible -- leaving the status of his 2017 season in the hands of the Fifth District Court.
If they rule in favor of Elliott, the soonest the NFL would see him sidelined would be 2018 -- if he sits at all. At this rate, it appears the league is running full speed into a brick wall.
