Games past, present, real and virtual dominate the weekend’s offering as March Madness looms and Daylight Saving Time begins.

Jerry Trainor and Jennette McCurdy of “iCarly” fame star in the original made-for-TV movie “Best Player” (7 p.m., Nickelodeon). Episodes of “iCarly” (6 p.m. and 6:30 p.m.) precede the new offering.

As on “iCarly,” there’s always a little cross-generational weirdness. Trainor plays a video game whiz who feels threatened by a younger rival (McCurdy). So he tries to throw her off her game by dating her mother. As I do whenever I see “iCarly,” I feel compelled to counsel Trainor’s character to grow up and find boys his own age to play with.

• The best sports documentaries are about more than the game. And “Runnin’ Rebels of UNLV” (8:30 p.m., HBO) is no exception. The film recalls the remarkable success of the University of Nevada at Las Vegas basketball team under its colorful, controversial and towel abusing coach Jerry Tarkanian.

From the early 1970s to the 1990s, Tarkanian took a school with absolutely no presence on the national stage and put it at the center of NCAA basketball. The Rebels would go the entire 1990-1991 season without a loss before falling to Duke in the Final Four. Tarkanian would lead his team to a 509-105 record, astonishing by any measure.

“Rebels” recalls the NCAA’s frequent and consistent efforts to discredit Tarkanian and his team for recruiting violations and other infractions. Rebel supporters argued that they were being singled out because of the school’s anti-elitist image and “Sin City” location. Tarkanian also had a habit of recruiting players with troubled pasts and for fielding teams with woeful academic records. Talk show host and Las Vegas native Jimmy Kimmel appears often to describe the thrill of the Rebels’ run. In a town that catered to visitors, Tarkanian’s team was one of the few things Las Vegas residents could call their own.
