CHARLESTON, W.Va. (AP) — Two years after TCU and West Virginia received a warm welcome into the Big 12, they've become the rude arrivals. The 10th-ranked Horned Frogs (6-1, 3-1 Big 12) and 20th-ranked Mountaineers (6-2, 4-1) are on a tear and making their conference neighbors nervous. They're chasing a league championship and one-loss TCU is battling for a spot in the four-team College Football Playoff. The newest Big 12 kids meet on Saturday in Morgantown in a game that highlights how far they've progressed.
