Racket contracts aren't huge right? Federer's contract with Wilson was worth around 4m per year when he extended it in 2017. Considering Roger's popularity in tennis world, this is likely to be the highest racket contract in tennis. So, any racket contract Emma is going to get will most likely be less than half of that. I just don't think the difference in racket contracts offered by various companies will be in millions. If it's a clothing sponsorship related contract like choosing between Nike, Adidas, Uniqlo etc, then I can see her switching for a better contract as these contracts are worth much more than racket contractsit's always been the case where they are making plenty of money from other contracts, but they always want more. If another company like Babolat offers her 10 year contract worth more than any other company can offer and this contract will stick even if she gets injured and has to take extended time off,,,, Then do you think she can refuse that ??? That's the kind of contract that babolat gave Rafa.
