Have the Broncos been professional grade in 2014?

Here’s my final #GMCPlaybook question for @SBNation this year: Did your team have a #ProfessionalGrade season? http://t.co/iQ1hxcHGwA

"This is it: it’s been quite a season here on GMC Playbook. Thanks for being creative and engaging with my questions. We’ve been talking all year about what it means to be GMC Professional Grade. Here’s my last question for you: Did your team have a Professional Grade season? If not, what will it take to get there next year?"

The Denver Broncos have 11 of 15 games this year. They are poised to earn the #2 seed in the AFC with a win against the Oakland Raiders, which would make them undefeated at home in 2014.

It would be the first time they've gone undefeated at home since 2005, and just the sixth time in their history accomplishing the feat ('05, '96-'98, '81).

But that means the 11-4 Broncos went 4-4 on the road this year, and that's the rub: the Broncos were professional grade when they played at home. They were something else when they played on the road.

While their road games against the Seahawks and Patriots were understandably difficult, their games against the Rams and the Bengals were surprising losses where the Broncos just didn't look quite right. They didn't look as well-prepared, and they weren't firing on all cylinders.

That's been the 2014 season so far: professional at home, shaky on the road. That doesn't bode well for a potential return to Foxboro, no matter what Pot Roast says.

The Broncos will have to improve their grade on both fronts if they hope to advance to Super Bowl XLIX in Glendale.
