Browns fans don't have many reasons to celebrate these days, but Richardson's performance is one of them. He has battled injuries throughout the season, so his overall numbers — 950 rushing yards, 367 receiving yards, 12 total touchdowns — don't look overwhelming. But when he's healthy, Richardson is a strong, physical back who can break a game open. If the Browns hadn't been trailing in so many games and forced to pass, Richardson could have done more this season.
