Rarely does change work out the first time around. But the College Football Playoff is one of those exceptions. Four is the perfect number of teams for the postseason. It keeps the significance of the regular season elevated and adds excitement without having to add more games that put players in harm's way.

Don't believe it? Just ask the players who put their bodies on the line for a chance to play a national championship. Here is former Alabama linebacker Reuben Foster, who won a national championship in 2015:

[Four] is the right number. It's a physical grind. It was hard, man -- tiring, beat up, but at the same time, it's football. But you don't want to [have] wear and tear with another game. What you've got to realize is when does the NFL hit every day at practice? They don't hit much. So we've got to get less of that [hitting in practice]. Really, they should cut it back.

Coaches, who have to deal with the grind of a football season, are also in favor of keeping the playoff to four games. Bill Hancock, the executive director of the College Football Playoff explains:

There are those who would like to see more teams in there to give them an opportunity for their teams, which I totally understand, but at the same time, they say, ‘But don’t take away our bowl experience.’ I think a lot of times, people who want a bigger field — which I completely understand — just want more football. That’s not a bad problem to have, but when you sit back and think about the importance of the regular season and the matter of not wanting the players to have to go back-to-back-to-back against quality opponents, then you realize that maybe four is the right number.

It's easy to look from afar and say what is better for a sport. But if the people who put their bodies through the grind are saying the field should remain four games, maybe people should listen.
