The more I think about this, the more I come back to South Carolina.
Even if you were to disqualify Alabama because of the quality of their losses, what about SC then? They also have an SoS in the teens, their losses were all to good teams, and they actually beat Clemson.
Head to head against SMU there's no real comparison, vastly better schedule, better wins, better losses. The only thing SMU has is a better record, but only due to an incredibly soft schedule which is easily demonstrated.
The committee is exactly what I've been saying they are. They chose solely based on what they wanted to have happen. They put their thumb on the scale, they broke with the polls, the broke with the computers, they chose inclusion over resume. The playoffs are now also exactly what I said they would become from the very start. This is about participation trophies, as the committee itself said when they cited SMU's conference record as justification for keeping them in.
It doesn't matter if your conference is crap (unless you're named Army), win those games and you get to go to the playoff. Quality of opponents does not matter.
