re: Does a 2 loss SEC team make the 4 team playoff ?

Likely. The other 3 slots will likely go to FSU(ACC Champ) and someone from the Big 12 and Pac 12. The only other real shot at beating the SEC out would be the Big 10. It would have to be Auburn or Bama, who has pull from recent success to jump a one loss Big 10 Champ. If its a 2 loss Big 10 or undefeated small school any SEC Champ would get in over them.
