Army, while ranked (#24), isn’t included in the CFP. It’s another snub like Florida State last year or Boise State in 2009. Army has one loss to Notre Dame.
Strength of schedule? That argument doesn’t hold when Indiana, 11-1, is placed at number 9 with three teams above it that have 2 losses on their records. And currently, Alabama is getting in with 3 losses. Army deserves a shot even if they would fail badly. Then again, they might surprise us and upset somebody . . . afterall, these are the men who are willing to fight for this Country. They are some of our best and brightest.
