Personally I think it's a bad move by JB. He was doing well at BAR. Also, I think he is risking his reputation and might start being seen as a "Me" man. After Williams comments about him during his time with them and now ditching the team hes done so well with I think people might start having second thoughts about making him offers next time his contract comes up for renewal and Williams don't want him. Then again maybe loyalty doesn't mean anything in F1. GTM
