I would argue (and I think most would agree) that there are limits on the lengths teams should go to try to win. For example, a coach should have an obligation to develop each player who commits to his program and puts in the effort to improve. Moreover, a coach has an obligation to be upfront and honest with his recruits. I see a recurring pattern at Quinnipiac every season now: a huge number of committed recruits, but most of those recruits end up held back in juniors or never see the ice once they ultimately matriculate. Instead, playing time goes to transfers and fifth years. Next season, the top freshmen like Pelosi and Schwartz will play; many of the others will (almost) never play. The result of which is a number of these recruits decommitting or transferring out of Quinnipiac after their freshman season. At the moment, Heisenberg lists Quinnipiac as having 26 committed players, including a significant number of '03s and '04s. Yet Quinnipiac will be bringing at least two players back for their fifth year and is also bringing in at least four transfers. [There is a huge back-log of recruits in large part because Quinnipiac has brought in so many transfers and retained so many fifth years the past few seasons.] Quinnipiac COULD fill its lineup with recruits, but they instead choose to bring back fifth years and bring in players from the portal. First of all, this is not what a "rebuild" looks like. Second, it's clear the program is willing to accept a high degree of player turnover in exchange for winning immediately. Now, is Quinnipiac the only team doing this? Surely not. But it's in stark contrast to the way other ECAC programs operate.
Clearly, taking a leading scorer from Omaha rather than playing a marginal freshman recruit is going to lead to more success, especially in the short-term. But this practice is going to lead to a high degree of player turnover, and probably some unhappy recruits/underclassmen. Yes, North Dakota and some other schools seem to operate similarly. I'm not really looking to argue about what is and isn't ethical; my main point is that Quinnipiac won't be rebuilding much next season. That's not how the program operates.
