Could be. Then again, a large portion of that salary for the hold-out year gets reclaimed.
Good luck to Zeke, if this is really what he's thinking. The last such RB to holdout missed the entire season and was forced to sign with the Jets.
Situation will be different, I believe. If Zeke holds out like Bell then he will never accrue the years to get to FA and get that Franchise tag. He can hold our of camp and games, but will have to show up eventually. Dallas can screw him by making him show up halfway through the season the next two years and then tagging him twice. Jerry isn't the vindictive guy I am, so he won't let it get to that point.
Or he could put feelers out to see if anyone will trade for Zeke.
