Grant Cohn: Steve Kerr walks the walk of a champ (w/video)

At Tuesday's press conference, Kerr, who also is 6-1, sat on a stool with his shoulders hunched. He rested his feet on the top rung of the stool so his knees came up to his bellybutton. He looked like a little kid. He looked like the un-Mark-Jackson.

Tuesday afternoon's press conference really was about the differences between Kerr and Jackson. You just had to look and listen closely.

Here is one of the first things Warriors general manager Bob Myers said about Kerr Tuesday afternoon. "When you strip it all away, what matters most is winning. And sitting to my left is somebody who has won at every level, and I don't think that can be understated. When you're around people that have won, it rubs off on you."

Translation: Kerr is a champion. Jackson is not. Jackson could lead the Warriors to the playoffs, but that was his limit. He doesn't know what it takes to win a championship because he never won one. Kerr knows what it takes because he won five as a player. He can teach Stephen Curry and the other young players how to become champions. Call it greatness by osmosis.

But Kerr never has coached a game in his life. Neither had Jackson when the Warriors hired him three years ago. Myers addressed this issue.

"The question that came up the most was how are you going to overcome your lack of coaching experience? Steve said, 'I'm going to work hard and surround myself with people that can help me get better, and each and every day I'm going to become a little bit better than the day before as a coach in this league.' For us, it was the right answer. It was confidence combined with humility, and we love that combination with Steve."

Translation: Jackson was confidence combined with arrogance. He was a coaching novice who thought he knew everything about basketball. He chose sub-par assistant coaches and he never improved. He had the same weakness after Year 3 that he had when he first started – no offensive system. Kerr knows what he doesn't know, and isn't afraid to ask for help from the very best assistants. He wants his No.1 guy to have head-coaching experience.

"These guys are fantastic," said Joe Lacob, referring to Myers and Kerr. "They're incredibly secure."

Jackson was not secure – that's why he had poor assistants. He was afraid an assistant would steal all of the credit.

Jackson also did not get along with upper management, including Myers. Jackson had an us-against-them attitude. "Us" being him and the players, and "them" being everyone else.

"The most important thing I've learned in sports is owner, GM, coach – the relationship between those three is critical," said Kerr.

Translation: Jackson didn't understand the most important thing in sports.

"What was special about the Bulls and what is still special about San Antonio is the strength of the organization," said Kerr, who should know. He played for Phil Jackson in Chicago and Gregg Popovich in San Antonio. "Both coaches constantly preached to us that it's not just the guys on the floor and the coaches, it's the entire organization."

Joe Lacob sat front-and-center nodding his head emphatically. Lacob liked what he heard. Kerr was saying all the right things.

Then the strangest thing happened. Kerr strayed.

A reporter asked if he feels pressure to win a championship considering Jackson was fired after winning 51 games last season and making the playoffs back-to-back years. Kerr shook his head.

"My view is not 'next year we've got to win 52 games,' or, 'we've got to get to the second round.' My view is, 'what are we going to do the next decade?'

" Lacob stopped nodding. He scratched the back of his head. It wasn't clear he liked what he was hearing. Does Kerr realize he's under contract for five years, not a decade?Kerr continued. "Having a swing at the plate year-in and year-out – that's what we're after here. Some years, that might mean we're a one seed. Some years, that might mean we slip out of the playoffs altogether. But I think everybody on the management side is on the board with that vision."Lacob scratched the back of his head vigorously. I highly doubt management is on board with that particular vision. Lacob just fired Jackson for not advancing far enough in the playoffs. Kerr can't miss the playoffs and keep his job. Kerr eventually has to win a championship. He admits he faces a learning curve. Here's the first thing he needs to learn. Slipping out of the playoffs is a bad idea.
