NEW YORK – Two hard-driving, enormously successful coaches shared a tender moment Tuesday night after Duke’s Mike Krzyzewski became the winningest coach in Division I men’s basketball.

Moments after career win number 903, Krzyzewski embraced Bob Knight, who coached him at Army and won 902 games in his career. No. 6-ranked Duke had just defeated Michigan State 74-69 at Madison Square Garden with Knight sitting in the ESPN color analyst’s chair.

Both men got choked up as Krzyzewski thanked Knight.

DURHAM -- A brilliant performance by freshman point guard Kyrie Irving gave way to stellar 3-point shooting for Duke in the second half as No. 1 Duke remained undefeated with a huge nonconference win.

Four 3-pointers in a span of 3 minutes, 40 seconds helped the top-ranked Blue Devils open up a 10-point, second-half lead Wednesday night in an 84-79 defeat of No. 6 Michigan State at Cameron Indoor Stadium in the premier meeting of the ACC-Big Ten Challenge.

At a Friday press conference, UNC basketball coach Roy Williams said his comments after Tuesday's win over Michigan State were taken out of context.

On Tuesday, Williams was asked about Spartans forward Delvon Roe, who Williams recruited, and his comments, which Williams said were misused, drew the ire of Michigan State coach Tom Izzo.

On Friday, Williams said he has "tremendous" respect for Izzo.

Michigan State is the lone Big Ten basketball program to have a winning record (5-4) in the Big Ten/ACC Challenge.

That distinction will be on the line this season when the Spartans travel to Chapel Hill to meet North Carolina in a rematch of the 2009 NCAA championship game. The Tar Heels defeated Michigan State 89-72 in Detroit in April.

The pairing is one of the highlights of the 2009 Big Ten/ACC Challenge. Game times and networks were announced Wednesday.

What do James Oblinger, Charlie Nelms, Richard Brodhead and Holden Thorp have in common?

Well, aside from the fact that each is a university leader here in the Triangle?

They're all men. Which in university fundraising right now may be a bad thing.

See, someone out there is dropping money upon college campuses all across the country. Anonymously. It's becoming quite the water-cooler mystery in American higher education. The latest recipient is Michigan State, which just got a whopping $10 million, with the caveat that the institution can't even try to figure out who the donor is.

In North Carolina, two universities have benefitted from this unusual largesse - UNC Greensboro and UNC Asheville. 

Both of those institutions have female leaders, as do all the other universities to receive mystery money lately, according to this Chicago Tribune report.

I can't help but wonder if this has caught the attention yet of Maureen Hartford over at Meredith College or Laura Bingham at Peace College.

You can bury the ghost of Kansas.

The only thing Tyler Hansbrough, Ty Lawson and this North Carolina group will be remembered for is winning the 2009 national title.

Well, winning the national title and playing maybe the best first half in the history of the title game.

A focused and determined UNC team dispatched Michigan State 89-72 for their fifth NCAA title and second in five years.
