The Browns have re-signed DE Simon Fraser and LB Mason Unck to 1-year contracts.  Fraser was a pleasant surprise for the Browns last season when he was pressed in duty because of injuries along the line.  He played in all 16 games last season for the Browns and he made 36 tackles, had 4.5 sacks, defensed 4 passes and forced a fumble.  Fraser will be in the Browns rotation at defensive end this season.  Linebacker Mason Unck is one of the Browns’ best special teams players.  He played in all 16 games last season and he made 13 tackles.  One thing Unck is good at is getting the crowd going before a kickoff.
