Former Rangers' coach Mike Keenan is in studio tonight for Rangers Game Night starting at 6:30 and throughout the evening alongside Bill Pidto during MSG's coverage of the Rangers and Senators. Keenan will answer your Twitter questions during both intermissions, and Michael Sauer will answer some in the first intermission (fans can Tweet questions to @thenyrangers using #NYR hashtag). Also John Giannone has a live bench-side interview with Brad Richards; Ottawa's Daniel Alfredsson discusses the hit from Wojtek Wolski which concussed him two weeks ago; and several Rangers players discuss the recent strong play of teammate Derek Stepan.
