He's looking for a similarly strong effort Sunday when his seventh-ranked Blue Devils try to improve to 8-0 all-time at home against Miami.
Duke (19-3, 6-1) won 83-76 at home over St. John's last Saturday, but Krzyzewski said the game "was a loss today for me'' afterward.
The coach ran the Blue Devils through two hard practices before Thursday's trip to Virginia Tech, and had a different outlook after a 75-60 victory.
"Our players felt really good after the game about our effort," Krzyzewski said. "They fought together and again, getting our fourth road win in conference is huge."
"Everybody's so unselfish now and it makes everything fun,'' Rivers said.
Krzyzewski also applauded his team's decision to not use Twitter for the rest of the season to minimize distractions at home, where the Blue Devils have never lost to Miami (13-7, 4-3).
"(The Hurricanes) have a lot of talent and we hope that we can put now two really good games together and play a great game at home," Krzyzewski said. "We'd like to play a really great game at home, have a great crowd, it'll be a really big-time ballgame."
Miami is seeking to win four straight conference games for the first time since Feb. 9-23, 2008. The Hurricanes have never won three ACC road games in a row within a single season.
"We're going to Cameron Indoor, that's going to be an incredible road test right there," said center Reggie Johnson, one of four North Carolina natives on the Miami roster. "So we gotta come with the right mindset for that game."
The Hurricanes blew a 16-point lead and had three players foul out before surviving for Wednesday's 90-86 double-overtime home win over Maryland. Durand Scott had a season-high 24 points, Malcolm Grant 14 and freshman Shane Larkin 12, with all three logging at least 39 minutes.
"I think we stick together as a team, for the most part, and did the correct things that coach (Jim Larranaga) told us to do to get this victory," Scott said.
Grant and Johnson each had 16 points in last season's 81-71 home loss to Duke. Krzyzewski is aware of what Miami brings to the table.
"They're 4-3 in our conference, big in size, Grant is one of the best 3-point shooters, Scott is one of the best penetrators, and their freshman Larkin has really become an outstanding defender for them," Krzyzewski said.
Miami forward Kenny Kadji could return after missing the Maryland game due to a head injury suffered during practice Tuesday. He's third on the team with a 12.5 scoring average and second in rebounding at 5.7 per game.
"He's a big part of this team," Scott said. "He gives us everything from rebounds, energy, points, blocks, just filling up the paint."
