The season is only four games old but the Buffalo Sabres' woefully unbalanced offense is prompting plenty of questions heading into today's game against the Washington Capitals in Verizon Center. • When will this team get any secondary scoring? The Sabres are 2-2 and have scored 11 goals in the four games. Each member of the top line (Thomas Vanek, Cody Hodgson, Jason Pominville) has three goals. That means the rest of the roster has combined for just two, by Steve Ott and Tyler Myers in the opener against Philadelphia. • Will Vanek even play today? He took a hard fall in the second period Friday night and suffered an undisclosed muscle strain, believed to be in his back or rib cage. "We talked this morning and he's doing OK," coach Lindy Ruff said after practice Saturday in the Northtown Center at Amherst. "We'll wait and see but I really anticipate he plays." • Wither Mikhail Grigorenko? The 18-year-old rookie played just two shifts in the final 40 minutes of Friday's 3-1 loss to Carolina. Today would be the final game he could play under his five-game junior tryout but Ruff said after practice Saturday that Grigorenko might sit out so the Sabres could buy some more practice time for him and not hit the five-game maximum.
