Say you’re an NFL player getting on in your career. You remember the days when you could plunge through the line 20, 30 times a game, post a dozen tackles, go all four quarters and overtime too. But now you don’t have the zip you used to. Sometimes you’re not even up for a game at all. It’s OK. It happens to a lot of players.
