TEMPE, Ariz. -- Arizona football coach Kevin Sumlin is returning for a third season in the desert.
Arizona failed to finish with a winning record or become bowl eligible in both of Sumlin's first two seasons, going a combined 9-15. The Wildcats opened this season 4-1 but closed with six straight losses, most in lopsided fashion.
Arizona failed to live up to offensive expectations after the fast start and finished among the worst in the FBS in total defense, scoring defense and passing defense.
Sumlin fired defensive coordinator Marcel Yates and several other assistants during the season. The defensive staff is expected to be mostly or completely new in 2020, sources told ESPN's Adam Rittenberg.
