There are a lot of similarities between Duke and Purdue.
For one, the Blue Devils have been underestimated all season long, while the Boilermakers are easily one of the most underestimated teams right now.
About a month ago this would have been even more of a premier matchup, with Purdue at full strength with a healthy Robbie Hummel and ranked in the top five.
However, despite Hummel's absence, Duke can expect the Boilermakers to give them all kinds of fits.
I cautioned right after Hummel's injury that it was unfair and disrespectful for any Blue Devil fans to take Purdue lightly.
They still are a very dangerous team with stars E'Twaun Moore, JaJuan Johnson, and a gutty Duke-like player in Chris Kramer.
Playing in the Big Ten, the Boilermakers won't shy away from Duke's physical nature of play and have enough athletes to give Duke's defense some problems.
So while the talking heads and the pieces of paper may hand an edge to Duke, there is a lot that makes me believe this will be a tightly contested game from tip to finish.
Here are some questions whose answers will be key to the outcome of what could be a classic tournament showdown.
