KANSAS CITY, Mo. (AP) — Ten years after firing Sean McDermott as his defensive coordinator, Kansas City Chiefs coach Andy Reid will stare across the field inside Arrowhead Stadium on Sunday and see his protégé trying to spoil his hopes of a Super Bowl repeat. That’s because McDermott has Buffalo playing in its first AFC title game since beating Kansas City on Jan. 23, 1994, when the Bills advanced to their fourth consecutive Super Bowl. Chiefs quarterback Patrick Mahomes appears to be poised to play after sustaining a concussion last week, setting up a tantalizing matchup with Bills counterpart Josh Allen.
