Not really. LSU needs a few thing to happen:
TCU needs to lose as that would ensure the Big 12, ACC, and PAC12 champions all have 1 loss.
From there, OSU and Michigan would need to have a one sided game result.
LSU making the playoff doesn't impact our playoff chances. At 11-1, we are #3 seed and a lock.
If LSU made the playoff, they'd be a 4 seed at best and UGA would drop to #2 with likely BIG 10 OSU/Michigan winner being the #1 seed.
If TCU drops a game, they are out of the top 10..... They have no good remaining opponents on their schedule (all 2 loss teams or worse) that they can lose to and stay in the top 10. So that is a spot LSU moves up to. From there it would be a game giving the #4 seed to 1 loss Clemson/UNC from ACC, 1 loss Oregon,USC,UCLA from PAC 12, or 2 loss LSU SEC Champion.....
Since LSU would have a loss to the #3 seed, that isn't a terrible loss even with the blowout. The committee would need to look at who had the best worst loss.... LSU losing on a missed PAT to Florida State, Oregon getting blown out by 46 points, or Clemson (and UNC for that matter) losing to a ND squad by double digits.....
Of course since Boo said they are looking for best teams first and not which conferences, that would involve looking to Vegas. Who would be favored in any of the matchups LSU vs 1 loss PAC12 champ, 1 loss ACC champ.... Same goes for PAC 12 champ vs ACC champ....
I don't find any scenario where a 12-1 Oregon/USC/UCLA or 12-1 Clemson/UNC would be favored over an 11-2 that just rattled off a 7 game win streak that included 3 top 10 wins.....
For the record, I don't think LSU has a chance in hell vs UGA..... I equate this year's LSU team to Auburn of 2017 that knocked off Bama 26-14 to go to Atlanta only get blown up by UGA in Atlanta by 3 scores.
However, if TCU drops a game, LSU at #6 or #7 in this week's rankings give them a small window. If they are in the top 6 when they play #1 UGA in Atlanta, a win would give them serious considerations at the #4....
