Peyton Manning can relate to the mental obstacles Andrew Luck will face after missing a full season.
Luck is expected to return this season for the Indianapolis Colts after missing all of 2017 with a right shoulder problem, which he originally injured in Week 3 of the 2015 season.
Manning missed the 2011 season with a neck injury.
"Everything is an individual thing, so you have to be careful speaking on it since injuries are different," Manning said. "But it's also universal. For me, I was a [repetition] guy. I liked to get all the reps on practice. The theory of 10,000 reps, I believe in that. I felt like I was kind of behind because I hadn't gotten the reps even though you have a lot in the bank. It took me a few games before I felt like I was coming back. Getting as many reps as possible is key."
Luck is currently limited in his participation during the team's OTAs.
"For me, coming off missing the entire year with the neck, I knew I was going to have to play a different kind of way, a different sort of physical state," Manning said. "I was looking for things like positive feedback from receivers on whether the ball felt the same coming in and then when you get into the game and you throw a deep out. We played a preseason game and I threw a deep comeback route, and that was a thing to check off the box. You want to do everything for the first time again. You want to get hit, you want to make a tight throw, have a two-minute drive. I wanted to do all those things again."
