Patterson (5-9, 200 lbs) was one of two tryout players who was not a rookie. He originally signed with the New England Patriots in 2015, but was released before the start of training camp. He later spent training camp with the Indianapolis Colts and even played in two games for them, registering two tackles. He was later waived and spent time on the St. Louis Rams' practice squad before getting a late-season call-up to make another tackle.
Patterson had just been released by the Rams on May 4, and about a week later he had a tryout with Cleveland. He's shown enough to warrant more than just a look by several teams, but now in his second year, will he do enough to stick with a club?
The Browns' website says the team is now at the maximum of 90 players, but something doesn't add up because their roster page still shows 91 players and we haven't heard of any other transactions.
