‘“The one thing we addressed the first day of training camp is we have to work,” Sabres coach Ted Nolan said after Monday’s practice. “We have to compete. We have to battle on a daily basis. We have to have some structure and discipline. To a man, they’re almost taking it to heart. They’re competing. They’re competing for jobs and they’re competing for ice time. When you have that going on, you’ve got a good environment.”’
