Over the course of the past couple of seasons, there have been times when Colts general manager Ryan Grigson and coach Chuck Pagano had differences in opinions.

Most were related to personnel, whether regarding the makeup of the roster or disagreements about which players should play certain roles.

But neither considers it a deep-rooted problem. Pagano's lack of a contract extension beyond this season and recent reports suggesting there are issues between the pair led to them issue a denial on Monday.

"It's hard enough to win in this league when everyone's getting along," Grigson said. "You've got no shot if you're not. It makes no sense for us to be going in opposite directions. That's not the case. Trust me. At the end of the day, we always do what's best for the horseshoe. Period."

Said Pagano: "We have no egos around here. Everybody checks them at the door every day they come to work. Players, coaches, myself, Ryan. The only thing that matters is the 'shoe and what's best for the 'shoe."

But here's what you should know about Grigson and Pagano. They do not always agree. This is a fact that is very well known by people inside and outside the organization. That is also not unique in the NFL, nor in Indianapolis. Tony Dungy and Bill Polian didn't always see eye-to-eye, but that didn't stop them from winning a Super Bowl together.

Furthermore, NFL history is littered with examples of coaches and executives who had disagreements, some more public than others.
