It was justified to let him go IMO. Suds- I think Jamie likes him- not sure letting him go happens or not- depends on what JP goes after. He spoke with Dave Smith when he hired Martin. I cannot see Dave leaving all of the talent that he has assembled in Stillwater. I still call Mike Smith at NAU and see if he will talk. Hiring Mark Carroll makes some sense as well.
I think you call Eric Heins who initially assembled the NAU squad that won the first (in 2016) of their 4 national titles in the past five years before handing it off to Mike Smith. Heins left the job at age 39 to follow his wife to Houston where she took a teaching supervisor job at the space center. Not sure what he's doing now but he warrants a call.
