Are you being intentionally thick? First of all, don't compare basketball with hockey. It's asinine and it gets you nowhere. You're comparing a niche sport with 60 D1 teams to the 1A/1B college sport in the country with 351 programs. You have 15 players on a college basketball roster and it only takes 1 superstar to make a run.
Second of all, buying tickets or paying tuition gets you what it gets you - a ticket or an education. You can demand whatever you want, you just look like an idiot. "Herr durr I bought this $12 ticket so I get input on a coaching decision with a six figure salary". Give me a break.
Lastly, you DO have to balance expectations with reality, regardless of what you want to believe. The reality is that Dennehy ran a good program. He got good recruits through the door. He helped the program survive back in the mid aughts when the administration was looking for a reason to drop down to AH or D3. He put a competitive team on the ice. He helped get that dumpster fire of an arena a respectable upgrade.
So my question to you is, who are you going to get that's better? You buy your tickets and paid tuition (I imagine) at some point, so here's your big chance to have your say. Who do you target? Who's the heir apparent that is both going to give as much as Dennehy did to this program and raise the success rate on the ice? Who's going to come into Merrimack with its handicaps and take on Hockey East and bring the Warriors to where YOU think it should be. Don't worry, I'll wait. Go Google some names and get back to me.
