For those who are fans of new ideas and shaking up the sometimes crusty thinking that runs prevalent in sports, the struggles Chip Kelly has endured in Philadelphia have to be a disappointment.

Say what you will about his roster management or schemes, but he was supposed to be the guy that came in with new ideas and challenged some of the industry norms. He’s the guy that makes decisions that jibe with mathematical equations. He’s the champion of the fourth-down machine.

In many ways, Kelly is like football’s version of the Oakland A’s during the early portion of the century. There’s little doubt now that some of the metrics being employed by A’s general manager Billy Beane at the time were correct.

Dissenters will say Oakland never won a World Series, so his methods didn’t work, but his ideas on on-base percentage and not sacrificing outs are common thinking now. Whether you like it or not, every team has been Moneyballed to some degree.

In a copycat league, if Kelly’s teams in Philadelphia were enjoying more success, there’s little question some of his ideas about when to go for it and other things would be more widely adopted, and we’d have a league that makes more mathematically sound decisions.

Whether that would be a good thing or a bad thing would be up for debate, but it’d at least force the league to challenge what is currently conventional wisdom. That can never be a bad thing.

But with the Eagles struggling, and Kelly’s seat growing hotter with each game, someone else is going to have come in with crazy ideas and find success to make that happen.

So, for now, it looks like you can expect your team to keep punting on fourth-and-2.

NICK’S PICKS: Underhill’s top five teams (this week)

1. Panthers (11-0)

It took longer than it should have to buy into how good this team truly is. If there are any doubts now, your hand has been forced. Can the Saints spoil their perfect season?

2. Patriots (10-1)

New England took Denver to the wire without Julian Edelman and Danny Amendola, and Rob Gronkowski was injured. Time to get healthy for the playoffs.

3. CARDINALS (9-2)

Carolina has the best record in the NFC, but something says Arizona might be the team to beat once the playoffs come around. Maybe the Panthers will prove us wrong again.

4. Broncos (9-2)

Don’t give Brock Osweiler the credit. He isn’t the sole reason this team is winning games, but he’s managing them well enough for the running game and defense to succeed.

5. BENGALS (9-2)

Cincinnati has looked more vulnerable in recent weeks, but bounced back in a big way with a suffocating defeat of the St. Louis Rams. Can this team keep it together?
