Duke Blue Devils got a whole lot better in a hurry

It is amazing to see how quickly a roster can change quickly.

When we last saw Duke, coach Mike Krzyzewski was cutting down the nets at the Final Four in Indianapolis. Many projected the Blue Devils would lose so much talent from that team that the future would not be very bright.

Duke did lose Jahlil Okafor, Tyus Jones and Justise Winslow to the NBA draft. Star guard Quinn Cook completed his eligibility. Suddenly the team's top four scorers were gone. Over 70 percent of the scoring from the championship team was gone. No double-figure scorers were scheduled to return.

Did Krzyzewski worry about his next squad? He simply went out and reloaded.

The Blue Devils had a lot of talent on the roster already. Grayson Allen showed his star potential in the NCAA final against Wisconsin. Allen will be a very special player next season. Amile Jefferson was a veteran up front capable of scoring and rebounding. Matt Jones showed flashes at times. Marshall Plumlee provided good minutes up front. A veteran nucleus was already in place.

Duke then went out and made more major additions. Forward Brandon Ingram, one of the top recruits in America, who participated in the McDonald's All-America game and Jordan Brand Classic, committed to go to Durham. Point guard Derryck Thornton reclassified to the class of 2015 and also joined Duke.

Add in prior recruits Luke Kennard and Chase Jeter and the Blue Devils now have the top recruiting class in the nation. Kentucky may still make a run at that distinction, but for now, the Cameron Crazies have to be ecstatic.

Kennard, who also played in the McDonald's All America game, Nike Hoop Summit and was selected to the Jordan Brand Classic, is eligible to be selected for the U.S. Under-19 team this summer. He is going to be very special, too.

With this roster makeover, there is now doubt that Duke will now be a legit top 10 team.

There is a reason that Mike Krzyzewski is a Hall of Famer. In my mind, he is the best coach in America. Adding a fifth national championship in April cemented his legacy. Now he wants more.

Krzyzewski is all about the next step. He is not about yesterday; he is all about today. The Duke basketball future is shining once again.
