1) “Young Rock” season-opener, 8 p.m. NBC. All four actors who play Dwayne “The Rock” Johnson are needed today. We see him as a kid and as a teen, idolizing a big-hearted, big-bodied dad (shown hee) who has little time. We also see him trying to break into Canadian pro football. And we see him in the future, played by the real Johnson. Those scenes, with Randall Park, are fairly funny; the others are merely interesting, treading a line somewhere between comedy and drama.
2) “Mr. Mayor” season-opener, 8:30, NBC. The mayor (Ted Danson) really wants some fresh ideas … but isn’t sure where to find them. He brings in an “innovation team,” with high-tech gadgets and high-sounding phrases. His assistant (Holly Hunter) is skeptical, his media guy (Bobby Moynihan) is overwhelmed and the others fret about job security, in an intermittently funny episode.
3) Basketball, 6:30 and 9 p.m. ET, TruTV. The NCAA tournament starts gently enough: Games today and Wednesday fill the last four spots in the 64-team field. One of the games is all-Texas — Texas A&M and Texas Southern; the other has Indiana — which elevated itself by reaching the finals of the Big Ten tournament — and Wyoming. Then things get busy Thursday and Friday; each day has four games each on CBS, TBS, TNT and TruTV.
4) “The Bachelor” finale, 8-10 p.m., ABC. Clayton Echard, 28, finally has to make a decision. It could be Rachel Recchia, 25, a flight instructor; or Gabby Windey, 30, an intensive care nurse. He told both “I love you” and/or “I’m falling in love with you.” Then again, he told Susie Evans, 28, the former Miss Virginia USA, “I am the most in love with you.” They fought and she left.
5) “The Thing About Pam,” 10 p.m., NBC. This fascinating true-crime story opened last week with Renee Zellweger stepping into the bizarre persona of Pam Hupp. In the opener, she gave a ride home to Betsy Faria … whom her husband Russ later found brutally murdered. Now Pam helps eager prosecutors build a case against Russ … whose lawyer is accustomed to working with guilty clients.
