Here’s five things to know about the matchup:

1. Rematch - MSU lost to Purdue 82-81 on Feb. 9 in West Lafayette, Indiana. In that game Purdue senior guard Rapheal Davis shot 6-of-8 from behind the 3-point line to go along with a monster 18 point, 13 rebound and eight block performance from senior center A.J. Hammons. MSU fell behind by as many as many as 16-points in the first half before battling back in the second half to force overtime. MSU lost the game in overtime as senior guard Denzel Valentine, who had brought MSU back from its large deficit with 27 points, 10 assists and eight rebounds, fouled Davis with just five-seconds to play in overtime. Davis made 1-of-2 from the free throw line and Hammons secured the offensive rebound and the Purdue win.

2. Purdue’s bigs - Plain and simple, Purdue is a terror inside. With a roster which features a pair of 7-footers in senior AJ Hammons and sophomore Isaac Haas, as well as talented freshman big man Caleb Swanigan, MSU’s bigs will certainly have their work cut out for them. That monster game from Hammons the last time these two teams played each other left a bad taste in some of MSU’s players’ mouth. Davis, Costello and company will have to contain what MSU head basketball coach Tom Izzo has described in the past as a “three-headed monster” if the Spartans hope to come out with a title.

3. Bryn Forbes shooting woes - After closing the season as the nation's best 3-point shooter at over 51 percent, senior guard Bryn Forbes has struggled so far in the Big Ten Tournament to find his shot. Forbes is shooting just 3-of-11 from behind the 3-point line over MSU’s first two Big Ten Tournament games, but he said Saturday after MSU’s win over Maryland he wasn’t worried about his shots not falling.

“I didn’t have any open shots, (Maryland) made it difficult,” Forbes said. “I’m not too worried about that, I know if I get some open shots I’ll make them.”

4. Offense looking to bounce back - In fact, not only has Forbes struggled offensively to find a rhythm, but MSU as a team struggled Saturday night against the size and length of Maryland. MSU shot just 42 percent Saturday night and made only six field goals in the entire second half.

MSU shoots the ball an average of 48.7 percent from the floor and MSU will face another tough test against the size and length of Purdue. MSU shot just 38 percent from the floor in its first matchup with Purdue, while having 16 shots blocked. MSU will be looking to redeem itself and get back on track offensively heading into the NCAA Tournament.

"We were so sorry on offense for the last 10 minutes," Costello said of MSU's game against Maryland on Saturday. "We can improve on that leaps and bounds. ... But other than that, our defense was good. But we need to clean up our offense."

5. MSU still locked in - Yes this game is technically a rematch. But you won’t find any of MSU’s players looking at this game from that perspective. It’s much more than that.

"This is a championship game," Valentine said. "And it's much more than getting revenge on Purdue. No disrespect to them. But we have bigger goals and aspirations. We want to win the championship. It makes it better because it so happens to be Purdue, and we lost to them earlier in the season. But at the same time, we're not worried about that. We're worried about holding that trophy up and them saying Michigan State Spartans are the champions. That's what we're worried about."

As for Costello’s view on all this? After hearing Valentine’s answer, he leaned into the microphone at MSU’s post game press conference Saturday and delivered about as short and simple an answer there is.

“What he said.”
