Tom Izzo watched on Wednesday as Villanova escaped with a one-point overtime win on the road at Seton Hall.As he listened to Wildcats coach Jay Wright being interviewed afterward, one comment stuck out.Winning close games this time of year is better than winning in blowouts, since close games are better preparation for the NCAA Tournament, Wright said.Izzo disagreed, enough that he called Wright the next day."I told him he was freaking crazy," Izzo said.But as he thought about it, Izzo said he came to see Wright's point.Wins in the NCAA Tournament rarely come easy, and winning close games gets easier with practice.If that philosophy holds true, then Michigan State is certainly getting plenty of practice of its own in winning close games.The Spartans' 63-60 win over Wisconsin on Friday in the Big Ten tournament was the Spartans' 13th straight win.Of the last eight games in that streak, six have been won by five points or fewer.In games decided by six points or fewer or in overtime this season, Michigan State is 8-0.On Feb.3, Matt McQuaid hit a 3 with 1:08 left to seal a three-point win over Indiana.Three days later, Michigan State came back from eight points on the road to beat Iowa by three.It beat Purdue on a 3-pointer from Miles Bridges on Feb.10.A week later the Spartans came back from 27 points down in the first half to beat Northwestern by five.And on Sunday at Wisconsin, Michigan State went on a late 11-2 run to beat the Badgers by five.At Madison Square Garden on Friday, it was McQuaid again who hit the biggest shot, a 3-pointer with 1:29 left to put Michigan State up by five after a back-and-forth second half."That's why we call him Big Shot Quaido," Bridges said.Those high number of close games hasn't exactly made Michigan State comfortable in the final minutes of a close game, point guard Cassius Winston said.But it has made them calmer and has produced more good plays than bad."I wouldn't say a comfort, but I think we're doing a lot better in those situations," Winston said."We're not panicking, we know the plays we have to make to win those type of games." Izzo said afterward that he was disappointed in his team's play and thought it looked out of sync.But he didn't seem to mind that his team played well once again in the final two minutes to close out a game.He also seemingly referenced the 2016 season, when the Spartans closed the regular season with six double-digit wins and then were upset in the first round of the NCAA Tournament by Middle Tennessee State.Deep down, Izzo may want to see his team winning more comfortably.But if wins like Friday's help him avoid a NCAA Tournament upset, then there's a silver lining."Winning a close game, you know, if we march on any in this tournament or in the next tournament, there's probably going to be a lot of close games," Izzo said."A couple of years ago we won by 15 in a lot of these games and we weren't ready for a close game.
