Jase, the contract bw button and BAR allows an "option" for him to leave to Williams should they fail the quota of 70% of the leaders points by turkey. In all fairness, this is most likely going to be the case, and that Button CAN go to Williams.

If I were him, Id be staying with BAR-Honda. They wanted him from the start, his worked closely with them, so there is no teething year, they have Hondas backing now, and they can only go forward.

Williams without a major engine supplier may be a problem, not because they dont have the technical know how, but the fact that BMW's funding is lost, they will need to purchase engines rather than be supplied with them. So many unknowns with the chance of Heidfeld leaving, that Id rather stay with BAR...

Im biased tho.
