Chattanooga, TN -- (Sports Network) - Armanti Edwards threw for three touchdowns, and Appalachian State captured its unprecedented third straight national crown by routing Delaware, 49-21, in the Football Championship Subdivision title contest.

The Mountaineers (13-2), who pulled off a shocker by beating Big Ten powerhouse Michigan on the road in their season opener, and won the Southern Conference, culminated the season with their 12th consecutive playoff victory.

ASU became the first Division I squad since Army in 1946 to win three national championships in a row.

The Mountaineers are undefeated in all three trips to the national championship game. The Mountaineers topped Northern Iowa, 21-16, in 2005 and defeated Massachusetts, 28-17, last year.

Joe Flacco threw for one score for Delaware (11-4), which was trying for its seventh national title.
