Editor's note: This file has been updated to include all games through Tuesday, Feb. 26.

This week's television coverage theme -- "Bracket Builder Week" -- is perfectly timed. This is typically the first week of Bubble Watch in which we're able, with at least some degree of precision, to look at a team's remaining schedule and reasonably posit where it might end up in the bracket discussion. With so few regular-season games remaining, we can be a bit more liberal in our use of those hallowed terms -- "locks" and "should be ins" -- and a bit more dismissive of long-shot teams who've failed to make definitive moves in recent weeks.

Such is the case in this week's Bubble Watch, which for the second straight week eschews a lengthy preamble in favor of getting right down to business. Onward:

----------

Atlantic Coast Conference

Locks: Duke, Miami

Should be in: North Carolina State

Work left to do: North Carolina, Maryland, Virginia

North Carolina State [19-8 (8-6), RPI: 24, SOS: 16] The Wolfpack have done plenty to earn their way into the tournament, and it would be a shock to see them somehow lose that status in the next few weeks, but they've also done just enough to prevent us from ever locking them in. Such was the case with their loss at North Carolina on Saturday. A win might have sealed the deal; a loss merely holds the line.

North Carolina [19-8 (9-5), RPI: 21, SOS: 11] The Tar Heels' three big wins in the past 10 days -- vs. Virginia, at Georgia Tech and at home against NC State -- didn't just add a couple of quality home victories against tournament-caliber teams and avoid a slightly ugly loss. It also helped boost the Tar Heels' RPI into the top 20s and added another top-25 RPI win (NC State) to a profile largely bereft of that kind of quality.

Maryland [19-8 (7-7), RPI: 67, SOS: 119] The Terps quickly undid many of the benefits they gained with the Duke win in their loss to Boston College last week, and their remaining schedule -- at Georgia Tech, at Wake, UNC, at Virginia -- doesn't bode particularly well. Are those winnable games? Sure. Are they loseable? Oh yes.

Virginia [19-8 (9-5), RPI: 69, SOS: 142] Meanwhile, Virginia remains much better than its RPI profile claims. Most efficiency-based metrics have the Cavaliers as a top-30 -- even a top-20 -- team; BPI puts UVa at No. 43. The RPI doesn't do this team justice, largely thanks to a few ugly early losses and some poorly chosen road drops (Georgia Tech, Clemson) in ACC play. With Duke arriving on Thursday, does Tony Bennett's team still have time to turn the tide?

Big East Conference

Locks: Syracuse, Louisville, Marquette, Georgetown

Should be in: Pittsburgh, Notre Dame

Work left to do: Cincinnati, St. John's, Villanova

Our next Big East move to lock status comes by way of the Georgetown Hoyas, who beat hated rival Syracuse in their last Big East trip to the Carrier Dome -- insert any and all Manley jokes here -- thanks to a POY-worthy performance from Otto Porter. The upshot is the Hoyas' already-strong resume was pushed into "no chance they miss the tournament" territory.

Pittsburgh [21-7 (9-6), RPI: 37, SOS: 46] The Panthers may never have materialized into the Big East title contender their early-season efficiency numbers suggested, but even after recent losses at Marquette and to Notre Dame, their NCAA tournament profile contains just one blemish: a road loss at Rutgers suffered back on Jan. 5. An 0-3 finish could possibly keep them out of the tourney, but I seriously doubt it.

Notre Dame [22-6 (10-5), RPI: 40, SOS: 94] Notre Dame is almost the anti-Pitt: If you look at the Irish's per-possession performance, their defense has been so bad (particularly in Big East play) that you'd expect them to be much worse off in the tournament picture than they currently are. ND's ugly nonconference SOS (269) could hold it back slightly, but otherwise things are looking good.

Cincinnati [19-9 (7-8), RPI: 50, SOS: 24] The Bearcats are this week's largest Big East downgrade, because while none of their past three losses are bad -- losing to Georgetown, UConn and Notre Dame are hardly tournament disqualifiers -- an ugly finish could cause the Bearcats no small amount of anxiety in the coming weeks. I'm not worried, but let's just wait and see.

Villanova [18-11 (9-7), RPI: 55, SOS: 37] Villanova's win over Marquette on Saturday was another big step forward for the Wildcats, their biggest since the back-to-back upsets of top-five-ranked Louisville and Syracuse during the same week in late January. And then ... Villanova lost to Seton Hall. One step forward, one step back. This team remains squarely atop the bubble.

St. John's [16-11 (8-7), RPI: 61, SOS: 29] Most current brackets list St. John's as one of the first four or eight teams outside of the tournament field, which seems about right: The bubble is soft enough that wins at Cincinnati and over Notre Dame and UConn are enough to put you in the conversation, but not so soft that a 4-8 record against the top 100 can go unnoticed. Almost the definition of a team that has work left to do.

----------

Big Ten Conference

Locks: Michigan, Michigan State, Indiana, Wisconsin, Ohio State

Should be in: Minnesota, Illinois

Work left to do: None

Pretty straightforward stuff: Wisconsin and Ohio State are going to the tournament. Both teams have a plethora of quality wins (especially UW), neither team has suffered many bad losses (especially OSU), and both teams have largely weathered the rigors of the best league in the country to an admirable degree. You can argue about their seeding, or whether each team's limits will hold them back in March, but let's be real: They're both dancing.

Minnesota [19-9 (7-8), RPI: 14, SOS: 1] Now, imagine if Minnesota could play like it cared all the time, huh? I'm guessing the Gophers wouldn't get blown out at Iowa (or Ohio State) and wouldn't have lost eight of their past 11 before Tuesday night's home stand against No. 1 Indiana. Minnesota came out hot against IU, riding a rowdy crowd, and it ended with the win that is sure to solidify what had become slowly sagging NCAA tournament hopes. Provided Minnesota doesn't lose to Penn State, Nebraska and Purdue in its last three, you can just about lock it up.

Illinois [20-9 (7-8), RPI: 32, SOS: 5] Illinois lost in relatively respectable fashion at Michigan on Sunday, and very little has changed in its tournament profile. Some committee members may distrust a team that went so cold for such a large part of the season, but the end-of-day body of work is what counts, and Illinois' wins -- especially over Indiana and at Gonzaga -- will eventually make it impossible to keep out of the field.
