Discernible changes were everywhere.
On the ice Friday, there was longtime NHL coach Bruce Boudreau's presence. Debuting his black Wild track suit, Boudreau pulled players over to the whiteboard at record pace and barked orders like, "Faster!" and "Come on!!!"
There was Hall of Famer Scott Stevens routinely pulling aside young defensemen for tutelage and the odd sight of free-agent addition Eric Staal skating around a training camp in something other than a Carolina Hurricanes sweater.
Inside the locker room, there were inspirational quotes. Vince Lombardi, Muhammad Ali, Jack Nicklaus, John Wooden, Roy Williams and Jerry West all have a corner. There's a framed sign called "Core Covenant" that includes a list of 16 things "we do all the time and hold each other accountable for."
"Everyone in hockey is like a kid at Christmas," Boudreau said after his first day of practices. "I had my skates on an hour before and I forgot to take them off in between [sessions]."
Training camp has started. As forward Charlie Coyle said, "There's a new way of doing things."
It was a first opportunity for players to show Boudreau and his staff, which includes Stevens and veteran John Anderson, what they can bring. On Day 1, the battles were already intense.
"The adrenaline [of the] first day, everyone wants to make a good first impression," Coyle said. "It's going to be physical, it's going to be a hard-nosed camp. Everyone's here to get a job and knock people out of their job. Everyone came prepared. It's good to see that intensity and competition right away. It's going to make our team better."
