Who says the college basketball regular season doesn’t mean anything? (Kirk Herbstreit and Mike Greenberg, I’m looking at you.)

When Dino Gaudio took over as the head coach at Wake Forest, he immediately announced a change in defensive philosophy. He decided that if the team wanted to become a perennial contender, they had to focus more on that end of the court. He implemented the Pack Defense, created by Dick Bennett, former coach at Wisconsin and Washington State. He spoke with Dick’s son, Tony, as well as Sean Miller, who uses the defense at Xavier.

That change in philosophy paid great dividends tonight, as the #4 Demon Deacons upended #1 Duke, 70-68, limiting the Blue Devils to just 4-22 from long range.

But good defense can’t always overcome bad free throw shooting. Wake Forest led, 61-48, with 8:50 to play. Benefiting from Wake’s 5-10 free throw shooting down the stretch, Duke went on a 20-7 run to tie the game at 68-68. The game should have gone to overtime, but Gerald Henderson, Nolan Smith and David McClure didn’t communicate on Wake’s out-of-bounds play with only a few seconds remaining, and James Johnson sprung free for a way-too-easy layup to win the game. Johnson was positioned to be the goat, as he was outhustled by Jon Scheyer for a rebound on Duke’s previous possession (which set up Gerald Henderson’s game-tying bucket over Johnson).

In the end, these were two very good teams doing battle in the ACC. Wake Forest now has the inside track to a #1 seed with wins over Duke and North Carolina, but the two teams will meet again in Durham on Feb. 22 and may meet a third time in the ACC Tournament.

In other action, #3 Pitt lost to #22 Villanova, 67-57. It’s tough to win any game on the road in the Big East, especially against a ranked opponent like the Wildcats. Reggie Redding led ‘Nova with 18 points as the Wildcats’ defense held the Panthers to just 42% from the floor and 20% from long range.

In one of those easy-to-miss-if-you’re-not-paying-attention weekday games, #1 Duke travels to Winston-Salem to face #4 Wake Forest in a big-time ACC showdown. The Blue Devils need to contain dynamic guard Jeff Teague and do their best to battle the Demon Deacons’ big men — James Johnson, Al-Farouq Aminu and Chas McFarland — in the paint. With improved play from 7’1″ center Brian Zoubek, Duke now has some extra beef down low.

The Demon Deacons have the home court advantage, but Duke is still a slight favorite, at least according to the Las Vegas oddsmakers. Wake Forest lost last week at home to Virginia Tech, but looked great in a Jan. 11 home win against North Carolina. Kyle Singler leads the Blue Devils in scoring (16.5 ppg), but lately it has been Gerald Henderson leading the way. He has averaged 21.0 points on 64% shooting over the last five games, so the Demon Deacons would be wise to account for him.

The game is on ESPN tonight at 7 PM.

There were five top 20 matchups on Saturday, and although there weren’t any buzzer beaters, there were some good games. Here are a few random thoughts…

– What is CBS thinking having Gus Johnson in the studio? He’s a capable in the halftime show, but he should be at the gym calling a game.

– #8 Syracuse blew out #13 Notre Dame, 93-74. The Big East is deep again this season and any win will be tough, especially on the road. Six Orangemen scored in double figures, led by Arinze Onuaku’s 19 points. Luke Harangody scored 25 points, but was a miserable 9-28 from the field.

– #2 Duke beat #12 Georgetown at home, 76-67. This game was close at the start, but a late first half run put the Blue Devils ahead, 40-29. From there, Duke simply managed its lead. G’Town cut it to five with 0:46 to play, but Duke made its free throws and coasted to the win. Gerald Henderson led the Dookies with 23 points and is looking more and more like an NBA talent.

– #3 Wake Forest won at #9 Clemson, 78-68. There was a great atmosphere at Littlejohn Coliseum, but the Demon Deacons passed the ball really well down the stretch to fend off the pesky Tigers. Clemson cut the lead to 61-60 with 4:54 to play, but Wake went on a 10-1 run over the next two and a half minutes to essentially put the game away. Jeff Teague led Wake with 24 points and five dimes.

– #15 Arizona State went into Pauley Pavilion and upended #7 UCLA in overtime, 61-58. Former North Carolina State head coach Herb Sendek has the Sun Devils playing solid basketball. They aren’t a very balanced team; James Harden (24 points) and Jeff Pendergraph (18 points) scored 42 of the team’s 61 points. UCLA simply couldn’t figure out the ASU zone in the second half, and didn’t score a single point for the last eight minutes of regulation. Including the extra period, the Bruins scored a total of four points in 13 minutes. Ouch.

– #20 Louisville upended #1 Pittsburgh, 69-63. Like I said earlier, winning on the road in the Big East isn’t going to be easy this season. There are a lot of good teams with strong home courts. Terrence Williams (20 points, seven rebounds, four assists) led the way for the Cardinals, and Earl Clark posted a double-double (16 points, 11 rebounds) on his birthday. It looks like Duke will be the #1 team in the nation come Monday, at least in the ESPN poll.

Everyone, meet Jeff Teague…

He’s a 6’2″ sophomore combo guard from Indiana who is averaging 20.6 points and 4.1 assists per game. Last night, in a marquee matchup with UNC’s Ty Lawson, Teague posted 34 points and four dimes to help #4-ranked Wake Forest pull out a 92-89 win over the #3-ranked Tar Heels. Teague completely outplayed Lawson — nine points, five assists, six rebounds — which makes one wonder why Lawson is projected to go in the mid-first round of the NBA Draft while Teague isn’t even on NBADraft.net’s draft board. Wait, there he is at #14…hmm…he wasn’t there last night when I checked. Does that mean, according to NBADraft.net, that Teague’s performance against North Carolina raised his stock from undrafted free agent to borderline lottery? It would appear so. (For the draft geeks, here is DraftExpress.com’s profile for Teague. They aptly compare him to Aaron Brooks and Louis Williams.)

Danny Green led the Tar Heels with 22 points, hitting 3 of 4 of his three-point shots. Tyler Hansbrough finished with 17 points, but only shot 3 of 12 from the field. The Demon Deacons’ big men did a nice job of keeping him from catching the ball in the post.

Wake Forest is a team to be reckoned with in the ACC. In addition to Teague, they have Al-Farouq Aminu (a 6’9″ lottery prospect) and James Johnson, who are both projected to go in the first round of the NBA Draft. Seven-footer Chas McFarland (who posted 20 points and nine boards last night) anchors the middle.

Wake Forest has a pair of tough road games coming up against Boston College and Clemson before coming home to host Virginia Tech and Duke.

How does this happen?

Two of the top four teams in the world of college basketball are facing each other today and the game won’t be on national television.

Apparently, the game is on Fox Sports Net, so you’re guess is as good as mine whether or not the game will be available in your cable package. You’ll have better luck if you have the sports package, but even then there’s no guarantee. It’s mind-boggling to me that a bigger network like CBS or ESPN didn’t step in and buy the game so that it could be broadcast nationally. It’s not like the great matchup snuck up on us — Wake Forest was ranked in the top 25 in the preseason and hasn’t lost a game all season.

Sigh.
