5. San Francisco 49ers
Can two seemingly obnoxious gentlemen coexist on the same team? We're talking about 49ers head coach Jim Harbaugh (who enjoys giving opposing coaches a firm handshake and a strong slap on the back, post-victory) and recently acquired wide receiver Randy Moss (who holds the "honor" of being jettisoned by three teams in a single season the last time he played in the NFL, back in 2010). The 49ers came oh-so-close to a Super Bowl appearance last year (they couldn't get past eventual Super Bowl champs the Giants in the NFC Championship game), and they are looking to get over the hump in 2012. But the question remains: will Mr. Moss hurt the team, or even bother to stick around?
