Championship Games, Rascal Flatts

Local college basketball fans still smarting from recent NCAA restrictions may find some resonance in "Runnin' Rebels of UNLV" (HBO, 9:30 p.m.), a new documentary about Jerry Tarkanian creating a major college basketball force in the desert before the NCAA lowered the boom on him. Like most HBO Sports documentaries, it's narrated by Live Schreiber and very well done.

Any UConn fan, though, will be watching the Big East Final (ESPN, 9 p.m.) with Huskies vs. Louisville. It's not the only local team in a big championship. It's UHart women at BU (CSN, 7 p.m.) in the America East final.

It's a good idea to pair a couple of the standout cast of "iCarly" in a TV movie, but "Best Player" (Nickelodeon, 8 p.m.) shows how tricky it can be to pair the funny Jerry Trainor with Jennette McCurdy. They play rivals at a video game, but he's much older than her. But is he old enough to be dating her mom to gain intel?

It may be the longest war in U.S. history, but at least they get this: "Ron White's Salute to Troops" (CMT, 9 p.m.), taped from the front lines of Nashville. Oddly, it overlaps with another of his comedy specials, "Ron White: Behavioral Problems" (Comedy Central, 10 p.m.).

"Rascal Flatts: Nothing Like This" (ABC, 9 p.m.) is a country concert special recorded at the Xcel Energy Center in St. Paul, Minn.

Karl Pilkington finishes his travels on "An Idiot Abroad" (Science, 10 p.m.) and chats with Ricky Gervais and Stephen Merchant about what he's learned.

Bobby Flay goes on a food tour to Ireland on the special "Bobby's Ireland" (Food Network, 9 p.m.).

New movies on cable tonight include Will Forte as "MacGruber" (HBO, 8 p.m.) and Russell Brand in "Get Him to the Greek" (Cinemax, 10 p.m.).

Last Sunday's premiere of "Secret Millionaire" (ABC, 10 p.m.) gets a rerun.

In the flurry of college men's basketball tournament finals, it's UTEP vs. Memphis (CBS, 11:30 a.m.) in Conference USA; BU vs. Stony Brook (ESPN2, noon) in the America East; Morgan State vs. Hampton (ESPN2, 2 p.m.) in the MEAC; Texas-San Antonio vs. McNeese State (ESPN2, 4 p.m.) in Southland; Arizona vs. Washington (CBS, 6 p.m.) in the Pac-10; Kansas vs. Texas (ESPN, 6 p.m.) for the Big 12 title; Akron vs. Kent State (ESPN2, 6 p.m.) in the MAC; Long Beach State vs. UCSB (ESPN2, 8 p.m.) in the Big West; Grambling vs. Alabama State (ESPNU, 8:30 p.m.) in the SWAC; UConn vs. Louisville (ESPN, 9 p.m.), of course, in the Big East; and Utah State vs. Boise State (ESPN2, 10 p.m.) in the WAC final.

Semifinals include Alabama vs. Kentucky (ABC, 1 p.m.) and Florida vs. Kentucky (ABC, 3 p.m.) in the SEC; Dayton vs. St. Joe's (CBSCS, 1 p.m.) and Temple vs. Richmond (CBSCS, 3:30 p.m.) in the Atlantic 10; North Carolina vs. Clemson (ESPN, 1 p.m.) in the ACC; Ohio State vs. Michigan (CBS, 1:40 p.m.) and Michigan State vs. Penn State (CBS, 4 p.m.) in the Big Ten.

Women's finals today have Louisiana Tech vs. Fresno State (ESPNU, 4 p.m.) in the WAC; Utah vs. TCU (Versus, 4 p.m.) in the Mountain West; Navy vs. American (CBSCS, 6 p.m.) in the Patriot; Prairie View vs. Southern (ESPNU, 6 p.m.) in the SWAC; Hartford at BU (CSN, 7 p.m.) in the America East; Central Florida vs. Tulane (CBSCS, 8 p.m.) in Conference USA.

In the women's CAA semifinals it's James Madison vs. Virginia Commonwealth (CSN, noon) and Delaware vs. UNC Wilmington (CSN, 2:30 p.m.).

Amid all of this (and it's not even "madness" yet) there is room for one NBA game: Lakers at Mavs (NBA, 9 p.m.).

In hockey, it's Islanders at Devils (MSG, 7 p.m.), Sabres at Maple Leafs (NHL, 7 p.m.) and Rangers at Sharks (MG, 10:30 p.m.).

But in spring baseball it's Marlins at Red Sox (NESN, 1 p.m.).

Zach Galifianakis has proven one of the best recent hosts of "Saturday Night Live" (NBC, 11:30 p.m.); he's back again for a new show tonight, with Jimmy J as musical guest.
