The 2018 regular season will conclude in Music City on Sunday night, where the Colts and Titans will play for a wild-card playoff berth. Or maybe more.

The winner between these 9-6 teams makes the playoffs. Should Houston (10-5) fall at home to Jacksonville (5-10), the Indianapolis-Tennessee victor earns the AFC South title.

That’s why two of the NFL’s more interesting but less glamorous teams were flexed to prime time.

But it’s an intriguing matchup featuring two rookie head coaches, Mike Vrabel for Tennessee, Frank Reich for Indianapolis, who know something about getting to and succeeding in the playoffs from their playing careers.

Unfortunately for them, neither of their teams has the pedigree that the Patriots would show when Vrabel was a linebacker for them, or the Bills in the 1990s when Reich was a quarterback.

Still, any game in which the winner gets into the postseason is worthy of the spotlight. Oh, and get this: Should Baltimore and Pittsburgh win and the Colts, No. 10 in the AP Pro32, and the No. 14 Titans tie, the Steelers grab the final AFC wild card. Why? Don’t ask.

With some uncertainty surrounding Marcus Mariota and his stinger — there is no betting line on the game because of it — plus the fact Andrew Luck is 10-0 vs. the Titans …
