If Belicheat couldnt get anything out of him, probably nothing to get. Particularly when you consider how bad O Line play has been in the league this year, and how desperate teams are to find guys.
He had a foot injury early in training camp and never was active for them after that. So he never even had a chance to show if they could get anything out of him.
"Cooper had been working with the first unit at right guard through spring practices and into the third day of training camp, when a foot injury sidelined him. He had just been removed from the team's injury report this week. While the Patriots had hoped Cooper would be their starting right guard, second-year player
Shaq Mason has seized the role, with rookie
Ted Karras also contributing. The team also has two guards on its practice squad for added depth: Chris Barker and Chase Farris."

Not saying he is going to amount to anything, but he really only practiced with the team for a few days before his release. Which ultimately could have been the reason he was released. Don't know what happened in his time with the Browns.
Did he ever even play in the league, like in real games? He was on the AZ roster because he was a first round pick and only that reason. NE gave up on him immediately. I guess Cleveland kicked the tires on him..
He played in 29 games believe it or not, and started 14 of them. Including the last 3 in Cleveland. And yes, I had to look that up.
