I don't know if he put in, but Caruso would be a good fit. His kids are out of the house and I don't know that UST has any immediate plans to move on from the PFL. It has to be tough going from the Athletic Department's top priority to an after-thought after UST decided to flagship hockey and basketball and build a new baseball/softball complex, while football mires in a non-scholarship league in the most fertile recruiting area in the MVFC. Caruso is a winner and familiar with the culture of the MVFC (though he coached at NDSU/USD pre-MVFC), and is an excellent recruiter.
That said, he's extremely comfortable in St. Paul, his job couldn't be more secure, and his wife has been battling some health issues. Guessing he's not going anywhere.
