The Browns have claimed 25-year old linebacker Blake Costanzo off waivers from the Bills.  Costanzo played in all 16 games for the Bills last season and he made 15 tackles and he forced 2 fumbles.  In his two seasons in the NFL, Costanzo has played in 19 games and he has made 21 tackles and has forced 2 fumbles.  Don’t look for Costanzo to play much defense if he makes the Browns’ roster but he is a special teams ace.
