"Good to go. That's what we do," Renney said. "That's the dynamic of the game.
"Whether it's in Year 1 of a rebuild or you're in your third year and you're starting to look serious about being a contender, it doesn't matter. The bottom line is a roster is a very dynamic thing. If you get too hung up on movement here, there or anywhere, that can, as a coach, really get in your way and stifle you from doing your job.
"Our objective is to make sure these guys stay focused. We have 19 games left and we want to make sure every one of them means something, that we come away better for it. That's our objective."
