This ^^^ bothered me enough to dig.
"If you think about the amateur draft, we have more access to video and higher-quality video than we’ve ever had. We have access to data, to things that will tell us about player tendencies, than we’ve ever had and we do have time now to really implement a data-driven player evaluation process, specifically over the last month I’ve really enjoyed working with Jeremiah and our scouting staff. They’ve been working hard in revisiting the 2020 draft and trying to incorporate more information, to be open-minded when it comes to evaluating players and I think also to develop a scout calendar and a process that can be a hybrid of both the data and the experts’ opinions, the scouts." —Jason Nightengale
"I would say the vast majority of information we take in – we have multiple data sources the league has used for a long time. We create our own proprietary statistics. We purchase third-party statistics. The majority of that data from a statistical standpoint is extremely noisy. I think it’s natural to have a vetting-out process and I think that’s one thing over the last seven years that’s happened. To me, it’s imperative on the analyst to earn trust with the hockey staff and to be able to put forward useful information that is predictive of success and repeatable." —Jason Nightengale
“I asked (Kevyn Adams why I was fired) and I think his words were, ‘clean slate,’ ” — ChrisTaylor
"As we build our scouting department, [we want to] sync up our scouting and analytics to become seamless and work together. There's a process that we want to go through in our scouting - both from the amateur and the professional side - of how we measure players, where we see value, what certain traits are we measuring, and at what level. That, from the analytics and the scouting, will be combined into how we ultimately move forward." —Kevyn Adams
"Obviously, you want hockey IQ, and the game is moving so fast right now, and to be able to process the game and understand it at a high level is extremely important. You need competitive, hard-to-play-against, resilient hockey players, and you need players that can skate. This league is fast right now, and you have to have players that can make plays and have puck skills — not just the obvious ones. It’s the little plays, the small-area plays, the plays that maybe the average fan may not even notice because it’s just through a guy’s stick or feet that it happens so quick. But that’s how the game is played now in tight areas. Those are just some ways of identifying how we will find Buffalo Sabres hockey players. —Adams
"When we look at the scouting and our player development and the analytics, like, how do we put all of those together to where they can work seamlessly together?" —Adams, in response to the question of how he decided who to keep and who to let go.
There's enough there for me to conclude that this was not just about cutting staff, it was about implementing a new method of player evaluation. There is no point in revisiting the 2020 draft if its just repeating the same process; there is no point in having open minds and striving to work seamlessly if previously there were no closed minds, or no seams showing.
He comes across a lot better in his personal interactions than Botterill ever did,
Hopefully there is more to it than that.
