What is the SEC tie in NY6 game this year?

It's the Peach Bowl, played on the night of Monday, January 1, 2018. The opponent will be the ACC runnerup who doesn't qualify for the playoffs.

Projected matchup: Auburn vs. Miami

I wonder, if Auburn loses to both UGA and Bama what happens

I feel that Auburn beats either Georgia or Alabama (if not both; they're both played @ Jordan-Hare), and even if LSU wins out, Auburn's resume would still be more impressive.

Sure, if LSU finishes 9-3 and Auburn 8-4, then the Tigers would go to the Peach!

However, I feel it in my bones that Auburn beats Georgia. They've been pretty impressive since the upset loss on Oct.14.

Yeah I feel like Auburn defeats Georgia or Bama as well

Would the NY6 take three sec teams when you include the playoffs? Obviously after Bama and Georgia

So it’s best for lsu if there are two sec teams in the playoffs. Gotcha

Possibly. Two playoff teams from the SEC, and the Peach for the Tigers if LSU takes care of business (no mean task, considering their past history of post-Bama collapse) and if one of the 3 remaining SEC players tanks the next 3-4 weeks.
