Denver Broncos QB Peyton Manning conceded that his arm isn’t as strong as it used to be entering Super Bowl 50 against the Carolina Panthers. ‘My arm is what it is,’ Manning said. ‘Honestly, my having a little time off to heal my foot helped some of the other parts. … My arm feels OK. My arm has not been the same since I was injured four years ago. … If I could throw left-handed it would be a lot easier. … It’s just different than it was. … It’s got a few yards on it, miles on it, however you want to say it.’
