"We won our first game on a last-second shot," the former Los Angeles Lakers point guard says in the ad. "I was so hyped. But the captain of my team said, 'Take it easy rookie, it's a long season, it's a long road to the championship.' He was right."
(According to NBA.com, that sage veteran mentioned in the ad who offers advice to a young Johnson is none other than Kareem Abdul-Jabbar, who happens to be publicly supporting Obama.)
"Whether it's winning championships or a president who can lead us back to greatness, I'll always want the most prepared and experienced person leading my team," Johnson also says. "That's why I'm asking you to join me in voting for Hillary Clinton for President.
The basketball great fails to point out the Lakers won the NBA championship his rookie season and he was named Finals MVP.
Johnson endorsed Clinton earlier in the year and campaigned at her side in the days leading up to the Iowa caucuses. He has also been campaigning with Bill Clinton in Nevada this week, and taking subtle digs at the Illinois senator.
"We need somebody who's not preaching hope," he said at one stop on Thursday. "We need somebody who understands that there's a problem, and they're preaching solutions."
