The Cowboys have paid him over a million dollars to be in training for 3 seasons.
They paid him a 53 man roster salary when he was on the practice squad which is about 500K instead of 100K.
Now after the Cowboys paid him to be trained to play football, he get's the opportunity to go to anther team with the 3 years of training 1 year of actual NFL game experience.
There is nothing he should be complaining about.
The Cowboys have no reason to favor a UDFA (Jarwin) or 4th round pick (Schultz) over him. They likely cut him because the new guy
Codey McElroy is beating him out.
