, show it to Nike, say our deal is way below market, match it or we bolt now.

If they say "no, read your contract" we say OK, we are bolting, feel free to sue us, and trust us when we say we will never sign a contract with Nike again in the future.

I will bet any amount of money that Nike improves things. I've never once had an unfavorable contract with a vendor (which is what Nike is) not be able to be renegotiated before expiration, even big vendors with thousands of customers and tons of negotiating leverage.
