UNLV last HC, Tony Sánchez, made $700k a year. Assuming they bump their next HC to $1 million (a significant raise) that would still be close to $1 million less than the Texas OC.
Obviously that doesn’t account for control of your own program, but still significant money.
UNLV is a low level Group of 5 job. I think if he stays 2 years at Texas he gets a low level Power 5 job or one of the high end Group of 5 jobs (UH, Memphis, Cincinnati, UCF, etc) and would make more money and be at place with higher chance of success.
USC seems destined to fall short. I still see hope at Texas. Plus he’s close to home, more comfortable recruiting, and more money. Granted he’s already been there so I can see him not wanting to jump.
But all in all I think Texas OC is the best job offer he has.
