I think you are misinformed about Marshall keeping its head coaches. The recently departed head coach, Dave Piepenbrink, was there for about 10 years. It was his assistant, Rick Reed (former MLB pitcer) who resigned earlier after just one year.
The big problem at Marshall has always been that they had horrible baseball facilities, but that is being addressed. Go to their web site and look for the information. A new on campus baseball field is being plannned, with an indoor practice facility that, while built with the football team in mind, will be available for the baseball team for practices when the weather is poor in January and February. the new coach is young, and from a solid program, so he should be able to move Marshall to a higher level (which it needs to be in the very competitive CUSA.)
