I'm sure if you had a job offer to do the same thing you are currently doing for 25% more money, you'd jump at the higher offer. So why can't Cobb do the same thing?
25% more than $9M is $11.25M. I think if Cobb gets an offer for more than that, he's clearly gone. If he gets an offer between $10-$11M/year...that is where it will be more interesting.
