Logical deduction for coach search (Long)

Remove unrealistic candidates or candidates who are too old/retired, remove coaches having success at a blue blood program, remove coaches making good money at their alma mater, and coaches with HUGE buyouts or coaching for universities with deeper pockets that will counter LSU:

This removes Day, DeBoer, Freeman, Elko, Saban, Meyer, Cignetti, Dillingham, Brohm, Key, Cristobal, Lanning, Riley, and Lea.

LSU could pull off a heist and nab one, but the likelihood of another Brian Kelly type hire is questionable. The only realistic candidates on that list IMO are Dillingham, Brohm, Key and Lea all who would be good hires, but let's remove them as part of the logical deduction because they are coaching at their Alma Mater.

Coaches left who are having moderate or better success listed by 1st tier (coaches at good programs ranked top 25), then 2nd tier (coaches in top 25 at mid programs), and 3rd tier (coaches from unranked mid or decent programs having some success):

1st tier - Kiffin(UM), Drinkwitz(Mizzou), and Heupel(Tenn) - all pricey to pull from competing SEC schools.

2nd tier - Sitake(BYU), McGuire(Texas Tech but may be too expensive for a question mark hire), Tony Elliot (UVA), Silverfield(Memphis), Fisch(UW), and Satterfield(Cincy).

3rd tier - Sumral(Tulane), Golesh(USF), Morris(UNT), Lashlee(SMU), Fritz(Houston), Aranda(Baylor), Fleck(Minnesota) Diaz(Duke), Dykes(TCU), Huff(USM), Harrell(ECU), and Rhule(Nebraska).

If LSU can't pull one of the tier 1 options, would you be happy (or at least satisfied) with any from tier 2 or 3?

I think of tier 2 and 3 coaches I would rank them:
1. McGuire
2. Diaz (For some reason I think he will be great at the right place)
3. Sitake, Fisch or Aranda
4. Fleck or Rhule
5. Elliot
6. All the rest from the mid G4 programs or not in the G4

After Tier 1, I hope LSU considers McGuire if possible or Manny Diaz!
