Arians’ Cardinals (14-3) and Rivera’s Panthers (16-1) meet Sunday for the NFC championship, with the winner making his first trip to the Super Bowl as a head coach. Arians parlayed his work as interim coach of the Colts in 2012, when Chuck Pagano had leukemia, into Coach of the Year recognition, then into the Arizona job. Rivera has guided Carolina to three consecutive NFC South titles, something no other franchise had managed. Look at his staff, with former players who played for him going all the way back to Temple, notes Herm Edwards, who got to know Arians when Edwards was a cornerback for the Eagles while Arians was at Temple. In his first stint with the Colts, Arians was quarterback coach from 1998-2000, working with Peyton Manning.
