Jed York has compared replacing Jim Harbaugh with Jim Tomsula to the Golden State Warriors' decision last year to fire Mark Jackson and eventually hire Steve Kerr. The Warriors went on to win the 2015 NBA championship, while the San Francisco 49ers are expected to take a step back in 2015.

"Culture is huge. That's the difference between a championship-caliber team and a championship team," York told The MMQB's Emily Kaplan. "You look at the Golden State Warriors. They were the dumbest team in the NBA for letting Mark Jackson go, who won the most games in the franchise's history. How could you be so dumb? They bring in Steve Kerr, who has been around the game for a long period of time but has never coached before. Kerr changes the culture, comes in with a different perspective, and look what happens."
