I am also an alumni to the baseball program from the early to mid 90's. When I was a freshman it was our first year in the MAC and we were terrible. Outmatched. By the time I left we made the playoffs twice and won the MAC tournament on Can't's field.
The facilities back then were nothing compared to now. We took indoor batting practice in a place we called "The Dungeon." Infielders took groundballs on the gym floor at Memorial Hall. Pitchers through off of wooden mounds made of 2X4's and plywood. We ran sprints in the bays at Rhodes Arena and had to help each other stop before we hit the walls. But, we did what we could and we got better.
Of course, facilities are a significant factor in recruiting. But they are not a determining factor in success and/or improvement. I only met Coach Bangston a couple times and do not know any of the players from his teams, but the facilities at Akron should not be an excuse. A new field, new grandstand, new backstop, new indoor cages and new wall will not make the team win. Leadership, teaching, hardwork and attention to detail will bring about improvement.
I went to a handful of games this past season and it was easy to see why they lost. Poor plate discipline (i.e. not working the count), routinely throwing behind the runners in the field, lack of execution on routine plays, pitcher's doing a poor job of holding runners, and a lack of leadership on the field are what I noticed the most. These are mostly mental errors.
In my opinion, the facilities are "good enough" to be successful. Besides, if you were running the athletic department, would you sink $500k into new facilities for a largely unsuccessful team? Or would you tell them to earn it first?
Also, you cannot move the backstop closer to home plate. It is already close by college standards and the field lacks in foul ball territory as it is.
