Final Four 2015: Updated Bracket, Picks for Tournament's Semifinal Matchups

There are two dandy national semifinals on tap for Saturday night, but the question on almost everyone's mind is whether the Kentucky Wildcats can complete the perfect season. If the Wildcats can get past the tough Wisconsin Badgers and the winner of the Michigan State Spartans vs. Duke Blue Devils, John Calipari's team will be 40-0 and the first undefeated national champion since the 1976 Indiana Hoosiers.

Referencing information from Draft Express and historic college hoops numbers, Stewart Mandel of CBS Sports tells us why this Final Four is significant.

Here's the most recent bracket, and just below that, are my predictions for the national semifinals.

Kentucky Will Beat Wisconsin

To put it simply, the Wisconsin Badgers don't have the athletes or the depth to influence me to pick them over Kentucky. This is college basketball, and anything can happen, but without insane outside shooting from the Badgers, the Wildcats should win this game more comfortably than they did against the Notre Dame Fighting Irish.

Notre Dame posed Kentucky issues because of how seamless it ran its offense, and it didn't turn the ball over much in the first half. Missed free throws cost Notre Dame the game late.

Wisconsin will bring its signature man-to-man defense, but it doesn't have the players to match up with Tyler Ulis, the Harrison Twins and Karl-Anthony Towns in one-on-one situations. KAT is likely to draw a double, but his willingness to pass out of those situations will leave the Badgers scrambling.

Kentucky will notch perhaps its most impressive win of the tournament on Saturday. It won't be the blowout win that it enjoyed over the West Virginia Mountaineers in the Sweet 16, but it will be a double-digit victory over a really good team. That's just as good.

Duke Will Turn Away Michigan State

Tom Izzo has done a great job guiding one of his lesser-talented squads this far, but the Blue Devils' size and clutch shooting will be the difference.

The Spartans don't have the interior defense to slow down Jahlil Okafor without double-teams, and that will open the game for slashers such as Justise Winslow and shooters such as Quinn Cook. The latter has been especially deadly from long range. He made 41 percent of his threes this season.

He had a tough shooting night against the Gonzaga Bulldogs in the Elite Eight, but he still managed to score 10 points in the low-scoring affair. 

This one should be close in the first half because of the way Izzo's teams always compete, but in the second half, I expect to see Duke pull away as the size and talent disparity begins to show itself.

The Duke win will set up the championship game most of us have been anticipating all season. Duke will get its chance to slay the Big Blue beast.
