Indianapolis ? The home of Tom Izzo’s greatest coaching achievement no longer exists.

All that’s left is the rubble.

He didn’t even know that the RCA Dome, where Michigan State won the 2000 national championship, was designated for demolition. Izzo’s hotel room for the Big Ten tournament two weeks ago overlooked the site and he looked forward to showing his 8-year-old son, Steven, where he won it all.

The kid wasn’t terribly impressed.

“He saw it,” Izzo said, “and was more interested in if he could play in the dirt.”

Rubble also was where the Spartans’ dreams of coming home for the Final Four lay buried Friday night.

And what rose from that crumbling mess just might challenge that championship night for one of the more glorious moments in Michigan State basketball.

The Spartans refused to lose, even when their lack of offensive execution suggested otherwise. They clawed. They battled. And when they needed a big play late, they put the ball in Kalin Lucas’ hands.

Michigan State’s stunning 67-62 victory over Kansas returns the Spartans to the Elite Eight for the first time since 2005. They’re one victory from the dance they have dreamed about and strived for since the first day of practice in October.

Izzo was justifiably irate at his team in the half, especially at Raymar Morgan.

It was an all-too familiar scene. Morgan turned passive. When the Spartans needed a veteran to step forward to calm some jitters, Morgan only added to the chaos.

Izzo reached the boiling point when Morgan, all of 6-feet-8, found himself at the top of the key against a much smaller defender. And rather than going strong to the basket, Morgan attempted a foolish pass and — there you have it — another Michigan State turnover and the Jayhawks suddenly led by 13.

Izzo called a time-out and glared at Morgan.

He didn’t play the remainder of the half. He sat through most of the second half, diagnosed with a poked eye. But Izzo curiously brought him back with less than 2 minutes remaining, and Morgan responded with a dunk off the baseline that knotted the score at 60. It was all Lucas then. Izzo wisely put the ball in his hands.

Still, considering how devastating Louisville looked in its annihilation of Arizona in the earlier game, getting to Ford Field remains an incredibly tall order for Michigan State.

But, at least, the Spartans remain in the discussion.

They’re still breathing, something most would have thought impossible considering how unrecognizable they looked in the first half.

The pressure of being two victories from a Final Four less than 90 miles from home got to them. They had as many turnovers (10) as they did field goals made (10) in that half.

The Jayhawks were much looser. There was less pressure on them because there had been fewer expectations.

Kansas wasn’t supposed to be here. The Jayhawks lost five starters from a national championship team. Even in college basketball’s rapid personnel turnover world, Kansas could have been forgiven for a relatively “down” season.

But instead the Spartans created another memorable Indianapolis moment. They’re 6-0 in NCAA Tournament games here.

Bring on Louisville.
