Rivalry spices competition. At the moment, the feud between Arizona State and Arizona is cayenne pepper.
Red hot.
The two football coaches, ASU's Todd Graham and Arizona's Rich Rodriguez, don't like one another.
After losing another shot at the Final Four, Arizona coach Sean Miller reacted to critics and trolls by blasting the ASU basketball program on Twitter.
"Finally to the people that try to make us feel like our season was a failure. Go cheer for ASU!"
And at the Bobby Hurley introductory press conference, an Arizona Daily Star reporter asked the former Duke star about the rivalry he just inherited, triggering some serious trash talk from ASU President Michael Crow.
