I believe at this point, there POHO role is important in the case of the sabres.
The organization is very far gone on all fronts. It has suffered from a lot of really bad structure and hiring that goes back to even before Pegula. Lots of friends and family plans there. Full of Pegula's little discoveries from the bowels of NCAA and USDP. We have a guy they found who was a Buff State assistant coach in charge of an undermanned pro scouting department for example. Amateur scouting isnt better-staffed either.
The job, IMO is too large for a typical General Manager. I would want the general manager being a bit more focused on the team on the ice, at least in the early stages until the foundation of the organization is built up and functional. A POHO can fix the structure and staff it with the right people, who also have experience and expertise to bring to the table. A POHO can also be the guy who speaks with Pegula and is a buffer between him and the rest of the operation, and the GM and coach will not have to speak with the owner every day.
A POHO, IMO, also opens the door to an older hire. While the front end is a bit busy, the job isnt as arduous as a pure General Manager. I would actually prefer the wisdom, credibility, and rolodex of a well respected hockey man in his 70s. The worst part of the job is probably talking to that guy from Boca Raton and dumbing everything down for him
