Louisville vs. Michigan State Prediction for March Madness Today

Sign up with March Madness betting promos and bet on Louisville vs. Michigan State with our Action Network expert prediction from Sean Paul. His Louisville vs. Michigan State prediction is Michigan State -4.5 (-110). Here's why you should place your first bet with the expert pick:

"This is your prototypical Tom Izzo team, with the Spartans ranking 13th in defensive efficiency per KenPom. And I expect one of the top coaches in college basketball history to create a plan to limit Louisville's shooting. … On average, Michigan State chops 18 seconds off the clock on defense, and teams shoot 3s 45% of the time against it.

Another Izzo staple is rebounding. This is one of his better rebounding squads, limiting teams to a 22% offensive rebound rate (the lowest nationally). On the other end, Michigan State grabs its misses 38% of the time — one of the top splits in the country, and it leads to it winning the shot-volume battle in most games. …

I'm laying the points with Michigan State. Sure, Louisville played well enough against South Florida, but having to battle the size of Kohler and Carson Cooper with the point guard play of Fears will make this a tough game for the Cardinals."
