The Sabres had plenty of roster moves to make in advance of tonight's game against the New York Rangers but interim coach Ron Rolston surprised the media during his morning briefing with another one: Jhonas Enroth will start in goal for the Sabres tonight because Ryan Miller has a sinus infection. Miller will serve as backup and he's expected to be fine for the weekend; the Sabres are off until Ottawa is here Saturday. Enroth, of course, came within 6 1/2 minutes of a shutout Thursday in New Jersey before leaving with coffee-induced cramps. "We sealed the coffee lids," Rolston joked. What's no joke is the coach wants to see the backup -- who remains winless since Nov. 26, 2011 -- try to put together a second straight solid game. "He's got to build off that game," Rolston said. "We'd like to see players be able to put things back-to-back, whether it's him or Grigorenko. Their job is to put the same product out there every night. ... I know it was one of the best games I've seen him play since I've been in the organization and we certainly want him to build off that."
