Kubiak works with VY, but realizes to take advantage of his special talents, he has to retool the offense.
The starting QB looks really good (Sage?) but Houstonians are intrigued with what VY does off schedule. The fans boo the starter like crazy and Kubiak is pressured to put in VY.
VY plays but struggles with the poor running backs and injured line and play calling by a newly formed staff. Many of the new Texan fans (who are more fans of VY than fans of the Texans) blame Kubiak for not taking advantage of VY's talents. The coaching staff has problems making VY follow all the rules because VY knows he is so popular in Houston, he can get away with anything. Maybe all his friends in Houston make it harder for him to focus just on football.
In year 3, Kubiak gets fired, and they look for another coach who will let Vince be Vince some more. Between finding the right scheme and trying not to get injured, the Texans end up with an exciting brand of football that ultimately disappoints. That the Texans are not a team, but rather the Vince Show, completely dependant on one player's health and good decisions off the field to do anything. VY never ends up living up to his potential, and he is either considered just a college wonder and bust or that the Texans ruined him.
