This is absurd.
1) Phil Jackson's won 11 NBA championships. That's an number in arguments like this.
2) Tex Winter's won zero titles at any level. He spent two decades getting fired everywhere he went until the Bulls hired him.
The head coach, not the assistant coach, runs the show. Winter coached the triangle because Phil Jackson wanted to run the triangle - Jackson put Winter into the Hall of Fame, not the other way around.
(And, not for nothing, but while he wrote a book, Winter didn't invent the triangle. He, like Jackson, added to it, but Winter's college coach Sam Berry invented it. He wrote the book before Tex Winter wrote the book. These days, there's also a guy coaching women's basketball who seems to be using it to win championships every year....)
