Denver Broncos quarterback Peyton Manning had multiple neck surgeries and missed all of 2011 season.
Upon his return last season, he threw for 4,659 yards and the second-most touchdowns of his NFL career (37).
"You know, I still have certain challenges," Manning said of the nerve issues in his neck. "When you're dealing with nerves, I've learned it's a patience deal. They kind of say it could be a year or two, or it may never come back, so I'm kind of hopeful. I kind of wish certain things would come back a little bit more, but I have learned to adjust and compensate in the state that I am. I still would like to make some more improvement. I still work at it.
"Obviously, I still can perform kind of status quo, but I still have hopes and (am) determined to try to seek some more improvement. But, yeah, I'm certainly better than I was last year. But I'm still not quite where I was before I was injured."
