I keep hearing that the Duke Blue Devils stand a good chance of earning a No. 1 seed in the NCAA tournament, and when I hear something like that enough times in March, even very early March, I tend to give it some credence. The NCAA tournament selection committee hands out those top seeds based in large part on the number of good wins that a team records (and on the number of bad losses that they do not suffer), and, as we'll see, on this metric the Blue Devils do indeed look very strong. But I'm here with a word of caution for you as you fill out your bracket this season. You should know that if Mike Krzyzewski's men do indeed earn a No. 1 seed, they'll be the weakest team we've seen on the top line in years.
