Krueger said his camp is divided into three phases, the second of which began with today's practice. While players took a day off Wednesday, the coaching staff prepared video from the team's two preseason games to use during meetings before they take on Toronto for a pair of contests this weekend.
Nelson offered a bit of insight into how the video portion of camp changed with a couple of games under their belt.
"Before we were just looking more at Team Europe from the World Cup, a lot of those clips, getting the groove on some of the more system-type things," Nelson said. "Now that we have a couple games we can look at some of the things we did well and anything we can change."
Krueger coached Team Europe - a collection of players from eight European nations - all the way to the championship game during the World Cup of Hockey in 2016 using an aggressive style that, in principle, he's now looking to replicate in Buffalo.
Nelson echoed several of his teammates in saying that Krueger's coaching philosophy will be conducive towards allowing players to operate instinctually.
"It's not straightforward systems that we're doing here," he said. "It's more of an outline, a lot of principles to go by, and then really he gives us a lot of the credit to just go out there and reply on our instincts. It's a lot of just playing, reading each other, staying connected.
"The more that we play with each other, against each other - even in practice - we feel more connected. We feel better and better each day."
