Sumlin says coaching Arizona is `the right challenge'

TUCSON, Ariz. (AP) -- Kevin Sumlin was introduced as head football coach at Arizona on Tuesday, calling it "the right place and the right challenge" for him.
The 53-year-old coach, fired after compiling a 51-26 record the past six seasons at Texas A&M, confirmed that he will retain Marcel Yates as defensive coordinator. He made no other announcements about assistants but there are consistent reports that he will bring in Noel Mazzone as offensive coordinator.
Sumlin, who also coached four seasons at Houston, takes over just 13 days after Arizona fired Rich Rodriguez after a notice of claim was filed with the state attorney general's office alleging he ran a hostile workplace.
