It's very hard to beat the Capitals at Capital One Arena. Washington has won 70 percent of its last 133 home games. The Lightning have lost in 37 of their past 54 visits to Washington.

Sharp coaching by Jon Cooper in changing up his lines. The combination of that and the Capitals being flat helped the Lightning defeat Washington, 4-2, on the road in Game 3 two days ago.

The Capitals may have let up and been overconfident returning home after winning the first two games of the series at Tampa Bay. Expect a much more focused and stronger effort from the Capitals. They will be better prepared and could get an additional boost with the strong possibility star center Nicklas Backstrom returns after missing the last four games with a hand injury. He practiced on Wednesday.
