He said three things drew him to Housley:
1. Organization. Housley is detailed and prepared. He plans short, high-tempo practices.
"That's where you have to draw from, and then the games, I believe, become a little easier, because you are prepared to play that way," Housley said.
2. Communication. Housley has connected with players on a personal level. That seems especially important when it comes to center Jack Eichel, 20, the No. 2 pick of the 2015 draft, even though Eichel has denied reports of problems with the previous coaching staff.
"It's about creating those relationships with your players," Housley said. "They've got to know where you stand, and you've got to know where they stand."
3. Track record in development. Housley coached in high school in his native Minnesota, was an assistant twice for the U.S. at the World Junior Championship, coached the United States to gold at world juniors in 2013, and was an assistant on Team USA at the World Cup of Hockey 2016. He spent the past four seasons as an assistant with the Nashville Predators, helping them make their first Stanley Cup Final appearance this year.
"He gets the most out of his players, the most out of the young players," Botterill said.
Housley coached perhaps the best top four defense in the NHL in Nashville: Mattias Ekholm, Ryan Ellis, Roman Josi, and P.K. Subban. In the Stanley Cup Playoffs, they fueled the offense while shutting down opponents like Patrick Kane, Vladimir Tarasenko and Ryan Getzlaf. He will not have Ekholm, Ellis, Josi or Subban in Buffalo, but as he said: "Those guys were young at one point too."
