Today is an extremely busy day so I'm going to dive straight into my hybrid review/preview for today.

First up, two new teams know they're going dancing.

Northeast - Robert Morris knocked off Mount St. Mary's, 48-46, after a titanic defensive struggle.  Dallas Green gave the Colonials the lead with 2.5 seconds left and the Mountaineers threw an interception on the inbound to send RMU dancing.

Big Sky - Portland State, the two seed, is in.  The Vikings, led by pint-sized powerhouse Jeremiah Dominguez's 22 and Julius Thomas' 17, knocked off sixth-seeded Montana State, 79-77.

Meanwhile, just about everyone on the bubble will be in action today.  Here's a brief rundown of these games.

ACC First Round (day session and 9:30 game on Raycom/FS Florida/Full Court, 7 pm game on ESPN2)

Virginia Tech vs. Miami (12 EDT) - This is a virtual elimination game for two teams who are right at the cut line.
Clemson vs. Georgia Tech (2:30 EDT*) - In my opinion, the Tigers seed is dropping because of their late season mediocrity.
Maryland vs. NC State (7 EDT) - The Terps beat the Wolfpack to open the month up.  They need to do it again to keep their hopes alive.
Boston College vs. Virginia (9:30 EDT*) - The Eagles should be in good shape if they get this one.

A-10 Quarterfinals (FS Ohio/MASN/Cox RI/CSN Philly for the day session, FS Ohio/MASN/Comcast Network, Cox RI for the night session)

Xavier vs. St. Louis (12 EDT) - The Musketeers need to win the A-10 to have a real shot at a protected seed.
Temple vs. St. Joseph's (2:30 EDT*) - This is a rematch of last year's championship game.  This year, only the Owls find themselves on the bubble.
Rhode Island vs. Duquesne (6:30 EDT) - The Dukes beat the Rams by 2 at the Palumbo Center to start off the month.  A loss here would end URI's at-large hopes.
Dayton vs. Richmond (9 EDT*) - The Flyers should be safe with a loss, but really shouldn't try to test that out.

Big East Quarterfinals (all games on ESPN)

Providence vs. Louisville (12 EDT) - Since the Friars' case wasn't helped by beating DePaul yesterday, this is an elimination game for them.  The Cards are looking to keep building their case for a one seed.
Villanova vs. Marquette (2:30 EDT) - The Golden Eagles finally won a game without Dominic James, in style, holding St. John's to 10 points in the first.  However, the Wildcats aren't the Red Storm.
Pittsburgh vs. West Virginia (7 EDT) - The Mountaineers all but ended Notre Dame's chances last night.  Tonight, they'll look to stop the Panthers' run to a one seed.
Connecticut vs. Syracuse (9:30 EDT*) - The Orange pulled away from Seton Hall last night.  They also look to be a roadblock to a team building a case for a spot on the top line, while working toward a potential top four seeding of their own.

Big Ten Opening Round

Minnesota vs. Northwestern (Big Ten, 12 EDT) - This is another virtual elimination game.  The Wildcats will probably need one more win if they get this one.
Michigan vs. Iowa (ESPN2, 2:30 EDT*) - A second loss to the Hawkeyes would doom the Wolverines to the NIT.
Penn State vs. Indiana (ESPN2, 5 EDT*) - The Nittany Lions swept the Hoosiers this year, but the second meeting, in State College less than two weeks ago, was a close one.  Like Michigan, PSU can't afford to drop this one. 

Big 12 Quarterfinals

Baylor vs. Kansas (ESPN2, 12:30 EDT) - A win here, and the Bears are back in the discussion.  Jayhawks need to keep winning to earn a two seed and, who knows, maybe even a slot in KC next weekend.
Kansas State vs. Texas (Big 12/Altitude/Full Court, 3 EDT*) - The Wildcats would be back in the frame with a season sweep of the Longhorns, with both wins away from Manhattan.
Oklahoma vs. Oklahoma State (Big 12/Altitude/Full Court, 7 EDT*) - The Sooners and Cowboys meet up for the second time in six days.  OU still has a shot at a one seed, while the Cowboys have a little breathing room after defeating Iowa State last night.
Missouri vs. Texas Tech (ESPN2, 9:30 EDT*) - The Red Raiders put a major dent in Texas A&M's hopes, thanks to a record-breaking night by Mike Singletary (43 points (tournament record), 29 consecutive TT points (2nd best in NCAA history)).  That's good news for the Tigers, as they beat the Red Raiders by 11 in Lubbock and lost to the Aggies by 10 on Saturday.

Conference USA Quarterfinals (all games on CSS)

UAB vs. Southern Miss (3:30 EDT*) - The Blazers still have slim at-large hopes, but they'll need to make the final.
Memphis vs. Tulane/East Carolina (7 EDT) - The Tigers are among the many teams playing for a one seed.

MWC Quarterfinals (all games on the mtn./CBS CS)

BYU vs. Air Force (3 EDT) - The good news for the Falcons, they repeated Colorado State's feat of going winless through the conference and winning the opening round game yesterday afternoon.  The bad news is they have to face a Cougar team looking to win the MWC tournament and improve their seeding.
San Diego State vs. UNLV (5:30 EDT*) - The Aztecs swept the Rebels in the regular season, making this a must win for UNLV.  It's also a must win for SDSU, whose non-conference strength of schedule is a bit of an issue.
Utah vs. TCU (9 EDT) - Utes are looking to improve their seeding.
New Mexico vs. Wyoming (11:30 EDT*) - The Lobos need to continue their hot play of late to make their way into the field.

Pac-10 Quarterfinals (all games on (FSN/selected CSN outlets)

Arizona State vs. Arizona (3 EDT) - This is an absolute must-win for the Wildcats.  The Sun Devils, meanwhile, need to win to stop their seed's freefall.
Washington vs. Stanford (5:30 EDT) - The Cardinal knocked Oregon State out last night.  Next, they'll try to stop the Huskies run at the title and up the S-curve.
California vs. USC (9 EDT) - The Trojans need to make a big run in this tournament to get themselves back in the conversation.
UCLA vs. Washington State (11:30 EDT) - The Cougars were unmerciful in putting an end to Oregon's season last night.  Next, they'll try for a repeat of their upset win over the Bruins back on February 21.

SEC First Round (all games on Raycom/Full Court/FS South/Sun Sports)

Kentucky vs. Ole Miss (1 EDT) - The Wildcats have absolutely no chance if they lose this one.
Mississippi State vs. Georgia (3:30 EDT*) - I'll refrain from making any bad Bulldog jokes here.  The question for the day is, can Georgia repeat their magical run of last year?  You know, the one that temporarily saved Dennis Felton?
Alabama vs. Vanderbilt (7:30 EDT) - Like I've said before, if you're talking about Auburn being in the discussion, you need to talk about the Commodores too.
Florida vs. Arkansas (10 EDT*) - Like Kentucky, the Gators cannot lose this one.  UF cannot repeat their performance against Alabama in this stage last year.

WAC Quarterfinals

Utah State vs. Fresno State (ESPNU, 5:30 EDT*) - Aggies look to start their run to a WAC championship.

The MAC tournament (which I will get to one of these years!) will also be on FS Ohio and FS Detroit.
