1) Basketball, 8:30 p.m. ET, CBS, with preview at 8. A no-upset tournament concludes. For the first time in 17 years, each team seeded No. 1 in a quadrant reached the final four. There’s no Cinderella team, no Butler or Bradley or Texas Tech or beyond. Instead, Duke, Florida, Auburn and Houston collided Saturday, with the winners tonight. Other networks will be quiet tonight — except for ABC, with “Idol” and (shown here) “Paradise.”
2) “American Idol” even on basketball’s big night, “Idol” tries a new episode. (NBC’s “The Voice,” by comparison, will recap its battle round.) This one involves head-to-head competition. On Sunday and next Monday, the show will be in Hawaii.
3) “Paradise” opener, 10 p.m., ABC. Here’s a quick transplant from Hulu. In an eight-part mini-series, Sterling K. Brown (shown here)– an Oscar-nominee (“American Fiction”) and three-time Emmy-winner – plays s a Secret Service agent for the president.
4) “TMZ Reports,” 9 p.m., Fox. Back in 1990, Lyle and Erik Menendez were arrested and charged with killing their wealthy parents. Now – 35 years later – they are 57 and 54, with a life sentence for murder. They also recently came close to having a new trial. “TMZ” interviews them and others, including lawyers and the arresting officer.
5) “The Hunting Party,” 10 p.m., NBC. This team keeps tracking super-scary people who escaped when a secret federal prison exploded. Now it’s Jenna Wells, known as the Killer Chemist, who did ominous things while she was imprisoned.
