Sweeney complimented the play of veteran blueliners Adam McQuaid and Kevan Miller during the 2016-17 season, in particular their ability to adapt to the changing style of the National Hockey League.
"He's not an easy player to play against," Sweeney said of McQuaid. "He continues to work on the parts of his game - the game's gotten faster and he's adapted very well to it. His aggressiveness and being able to defend the blue line and entries last year is a testament to him continued to adapt."
"Kevan Miller's another good example of a similar ilk of player, but they continue to evolve…and they haven't sort of rested on what they were in the league, especially as the league around them changes," added Sweeney. "It's a testament to them as individual players."
Miller, who was one of the B's most valued defensemen during the second half of last season, has continued to amp up his training as he seeks to improve all facets of his game.
"He's hired people in the summer time to continue to work on his game. He wants to continue to get better as a player and he believes he can," said Sweeney. "He's in absolute peak physical condition. You're not going to find a guy that works any harder on that in every facet of his game, so he's not leaving stones unturned to continue to become a better player.
"Again, a testament to his character. Again, the intangibles, the intestinal fortitude probably got him the opportunity to begin with, but now he's made himself into a valuable player in the National Hockey League."
