NBC tries to climb out of the ratings cellar by bringing back two of its few hits show tonight, and the BYU men's basketball team tries to keep its season going for at least another couple of days.The Cougars host Mercer in the second round of the National Invitation Tournament (7 p.m., ESPNews) - and, yes, that's the correct channel. That's Channel 402 on Comcast; Channel 207 on DirecTV; and Channel 142 on Dish.If you don't get ESPNews, the game will be replayed at 10 p.m. on BYUtv and at 11 p.m. on ESPNU/Over on NBC, the blind auditions begin on the new season of The Voice (7 p.m., Ch. 5). And half the judging panel has been switched out - Christina Aguilera and Celo Green are gone; Usher and Shakira join Adam Levine and Blake Shelton.NBC programmers made the decision to put one of its few successful shows, Revolution (9 p.m., Ch. 5), on hiatus for a full four months so that it could continue to air after "The Voice."You can easily make the argument (and I have) that much of "Revolution's" success can be attributed to its lead-in. But a four-month hiatus can kill any show's momentum.We'll see if NBC's decision was the right one.Elsewhere on TV ...How I Met Your Mother (7 p.m., CBS/Ch. 2): Marshall challenges Robin to a dance-off.Dancing with the Stars (7 p.m., ABC/Ch. 4): The remaining contestants perform.Bones (7 p.m., Fox/Ch. 13): An undercover cop turns up dead with a bag of diamonds inside his body.The Carrie Diaries (7 p.m., CW/Ch. 30): Carrie assumes Larissa's identity.NBA (7 p.m. ROOT): Philadelphia 76ers at Utah JazzBeing Human (7 and 10 p.m., Syfy): Aidan breaks Kenny out of the hospital.Dallas (7 and 9 p.m., TNT): Pamela's mother - Afton Cooper - returns to Dallas.Rules of Engagement (7:30 p.m., CBS/Ch. 2): Timmy pointedly excludes Russell from a dinner.2 Broke Girls (8 p.m., CBS/Ch. 2): Caroline is fired.180 Days: A Year Inside an American High School (8 p.m., PBS/Ch. 7): Fascinating, disturbing documentary that goes inside an underperforming high school in Washington, D.C.
