SUMMARY: Tennessee Titans coach Jeff Fisher recently explained the biggest lesson he has learned while becoming the NFL's longest-tenured head coach with one team. "Things come up on a daily basis that are going to occupy a lot of your time, and they're not necessarily related to X's and O's," Fisher said. "That's the thing I didn't realize, I thought it was all about the X's and O's." For Fisher, the game hasn't changed much since he was a defensive back for Chicago in the '80s, but the players have.

"There are more players now than there were in the past that need to learn how to respect the opportunity they have been given."
