the current coaching staff found him completely unreliable, justifiably since he missed 21 of the first 22 games they were here. I kind of get his release although dumb and dumber completely telegraphed his departure so they got zilch for him.
I still can't comprehend the Amari Cooper situation. He's now like the 11th highest paid WR in the league, so they failed to read where the market was trending (no surprise!), they got next to nothing for a still productive threat, he's 28 years old, and they essentially failed to deal with that replacement wise. And Jed Clampett can talk about "availability" all he wants but Cooper played in 56 of a possible 58 games for the Cowboys.
