The Wire-to-Wire Club is now in session. Notice how we won’t need many chairs.

Admission is simple, but hard. Very, very hard. There are only three requirements.

Be the No. 1 ranked team in the first college basketball poll.

Stay No. 1 all season.

Win the national championship at the end.

Not a lot margin for error in that process, is there? This in contrast, say, to the nine national champions who started the season unranked – 2011 Connecticut the last one.

The San Francisco Dons of 1956. Say hello to Bill Russell.

The UCLA teams of 1967 and ’69. Welcome back, Lew Alcindor, only now the name tag says Kareem Abdul-Jabbar. The ’69 Bruins actually lost their last regular season game to USC, by the way. But back then, that was after the final poll, so there was no worry about losing No. 1.

UCLA of 1972 and ’73. Good to see you again, Bill Walton.

Indiana, 1976. Yes Hoosiers, we know. You’re still the last unbeaten champions.

Duke, 1992. Who somehow managed to stay No. 1 while losing two games during the season.

And that’s it. Seven teams in all recorded history. That’s how distinguished the group is before us. It didn’t take long this season to know there would be no new face added in 2018; as quick as you could say Boston College 89, Duke 84. That loss on Dec. 9 knocked the Blue Devils from the top spot.

How hard is it to accomplish, when you have a target on your chest from the first moment of the season, and wear it for five months? We can ask a couple of guys who did it.

Quinn Buckner, from 1976 Indiana, for instance. The road to the Wire-to-Wire Club began the March before, when the unbeaten Hoosiers were knocked out in the regional championship game by Kentucky.

“I don’t know if you can be any more of target than being No. 1,” Buckner said. “The real genius was the way Coach (Bob) Knight diverted a lot of the attention by some of the things he did. I would guarantee you if he thought we were starting to feel pressure, he may act out one way or another. The press tended to follow him and he kept us shielded as a rule from the press.

“Being No. 1, he actually put it on us even more. Coach said that we couldn’t be satisfied with winning the Big Ten or winning the NCAA, we had to do it undefeated. From there, you just play. “
