Unless it has changed, here's a rough rank ordering of the SEC bowl tie-ins:
- Playoff
- Sugar (if not a Playoff Bowl)
- Orange (if not a Playoff Bowl -- slot shared with B10 or ND)
- Citrus
- Outback
- Music City
- TaxSlayer/Gator
- Liberty
- Texas
- Belk
- Birmingham
- AdvoCare v100
Everything from Outback to Belk are technically co-equals, I think, because the Conference has free rein (by prior arrangement with all those bowl committees) to select which team goes to which bowl. But in reality, I think the prestige of them runs more or less in the order above.
Assuming the SEC Champ (Auburn in this scenario) gets into the Playoff (Cotton or Orange, in 2015), the next option open for Tennessee is the Sugar Bowl.
Could be that another SEC team ended up higher ranked than the Vols, though, with something like a 10-2 record, though they didn't get to the SEC CG. So that team could get the Sugar Bowl invite instead.
That makes the 10-3 Vols a lock for the Citrus Bowl in this scenario. I think. Unless some arrangement has changed in the off-season.
