Until we actually see Peyton Manning throw, we can only go by what coaches and teammates are saying about the quarterback who had a cervical fusion in September.
Broncos wide receiver Eric Decker has been working closely with Manning for the past couple of weeks and this is what he said on ESPN Radio:
"“The guy’s still throwing the ball a long time, throwing it great, hitting you in the right spot,” Decker told Cowherd. “He’s such a perfectionist. If he hits you in the belly button, he gets mad at himself for not hitting you in the chest. It’s unbelievable to be around a guy who has those standards for himself.” – Eric Decker via ESPN"
Decker went on to talk about Manning’s work ethic.
"“He’s so precise with everything he does and there’s a reason for everything he does do,” Decker told Cowherd. “In workouts, in the weight room — I mean the guy’s jogging from station to station. He’s working like he’s a 23-year-old free agent coming out of college. The way he talks about football, the way he runs drill work, routes, everything’s gotta be perfect and there’s no gray area. I think that, as a receiver, [is] the best thing about it. You got a leader that demands the best out of you because he gives the best he’s got.”"
