Sports bar near 3 muses?
If you want to stay near Frenchmen, BTW, it's "men," not "man," Turtle Bay on Decatur between Ursulines & Gov. Nicholls (just a few blocks away) has multiple screens, would very likely turn on the NHL playoffs if they're not already showing them, and has a great beer selection and friendly bartenders.
Maison sometimes has a game on their TVs, you might be able to put in a request. Although I couldn't promise results, the John (at the corner of Burgundy) or the Lost Love Lounge (on Franklin and Dauphine -- one of the owners is from Chicago) might also put the game on for you. As a whole, this isn't a hockey town.
That said, in the upper Quarter, Ryan's seems to attract a hockey crowd (and pours a fine pint).
