Not taking away anything from the drivers. All of them are exceptional and possibly the best on the planet.
That said, when you are racing over ~20ish races , as a team, it pretty much boils down to long term strategy and tactics.
Kevin Schwantz and Wayne Rainey were 2 epic motorcyclists in the 90s. Schwantz had more individual wins, but it was Rainey that had more championships titles, because he was more consistent in his races and made fewer mistakes (Even Schwantz admits this in an interview)
