According to ESPN, Muschamp met with athletics director Jeremy Foley, who offered him the job.
Muschamp's SEC ties are notoriously thick — he graduated from Georgia and was defensive coordinator at both LSU and Auburn before coming to Texas. Additionally, Muschamp began his coaching career as a graduate assistant at Auburn.
Muschamp's stays at LSU and Auburn were split by a one-year stint as the Miami Dolphins' assistant head coach for defense.
Muschamp is widely considered one of college football's top defensive minds. His SEC defenses all ranked in the country's top-10 in either scoring defense or total defense. His three Longhorn defensive units have led the Big 12 in total defense each year.
This year's defense struggled at times to stop the big play, particularly against the run, but still managed to finish first in the league by allowing 300.2 total yards per game.
The Longhorns weren't as good at keeping teams off the scoreboard, finishing fifth in the conference in scoring defense at 23.7 points per game.
Muschamp was also the Longhorns' coach-in-waiting, but was somewhat publicly undercut by Texas head Mack Brown, who said he would be making all of this year's staff change decisions without say from his No. 2.
