Successful organizations fire or lay people off all the time. The notion that BU has financial problems is laughable.
Unsuccessful or underperforming organizations fire or lay people off even more frequently, potty.
In the big picture, I doubt BU has "financial problems" too, but clearly they've determined they either have a short-to-mid term profitability and/or liquidity issue.
There's nothing in their mission statement that goes directly to profitability being a bad thing, but all in all, academia likes to hold themselves out as focused on other, more lofty goals, to wit "higher education should be accessible to all and that research, scholarship, artistic creation, and professional practice should be conducted in the service of the wider community—local and international. These principles endure in the University’s insistence on the value of diversity, in its tradition and standards of excellence, and in its dynamic engagement with the City of Boston and the world." No mention there of keeping up with the Joneses of HEA/D-1 Hockey.
BU doesn't enjoy membership in revenue-generating conferences such as the ACC, the Big Ten or even the Big East. In that way, it's not all that different from NU, UNH, UMaine, the two UMass schools (especially Lowell) or UVM. And it doesn't appear BU is gonna touch their billion gazillion dollar endowment to bail out 120+ of their own valued employees ... so why would anyone assume they'd be willing to dip into that pool to fund their newly minted, semi-professional athletes, any more than (say) Harvard and Yale, who also swim in similar if not identical low revenue conferences.
A cautionary tale perhaps ... the gentleman whose name is on BU's relatively new, close to state-of-the-art arena was NOT a hockey guy. Harry Agganis was a BU All-American quarterback, who played baseball for BU in the Spring, and eventually chose the then-lowly but local Red Sox over the NFL Champion Browns who had drafted him in the first round of the NFL Draft with an eye towards replacing aging veteran HOF QB Otto Graham, a/k/a the TB12 of post-WW2 pro football.
Had he been born in modern times, "The Golden Greek" couldn't have even played either of his two pro-level sports at BU. Things change, sometimes rapidly.
Once again, you've made some faulty assumptions about the likely "haves" and "have nots" of this brave new NIL world that's been thrust upon HEA.
