Martin has done a remarkable job, and there may not be a more popular and respected individual in the Oregon athletic department. After the Ducks won the 2016 national title, it was reported that a contract extension was in progress. However, the UO public records website includes only his five-year contract that expires at the end of this month at a guaranteed base salary of $170,000, plus incentives. Clearly, he is due for a substantial raise with his new contract.
Just for comparison's sake, here are some random coaches' compensation (salary, bonuses, benefits) from last year at various Ohio universities provided by cleveland.com:
Ohio State women's golf -- $230,183 
Kent State men's golf -- $245,402
Bowling Green men's ice hockey -- $255,999
Ohio State men's tennis -- $327,799
Ohio State women's rowing -- $366,157
Martin's new deal should fit in there nicely. Those screeching that he's unappreciated are better off ignored.
