When Jackson was appointed head coach in 1989, the first thing he did was to introduce the Triangle Offense, a complicated strategy that emphasizes movement without the ball. It did not take at first. He brought in the foremost exponent of the Triangle, Tex Winter, and continued to sell the recalcitrant Bulls. The proselytizing paid off as the Bulls won their first championship in 1991 and added five more flags during the decade, before Michael Jordan retired. And I think that's a factor, too, because of the time it takes again for a team to not even master it, but to feel comfortable doing it.
Sports teams are notorious copycats for success.
Jackson is also outspoken on the negativity of the media. Jackson, a man who was once part of the media as a color commentator on radio and TV, doesn't really seem that upset. The spectacular is always emphasized, which I guess it has to be when you show the highlights. Jackson's elevation to head coach of the Bull also put a strain on his longtime relationship with Rosen. Jackson almost hired him as an assistant coach in Chicago, but the deal fell through.
