Probably none of it.
Bryant didn’t have a significant injury history prior to signing with Colorado, so it’s unlikely the Rockies would have taken on the kind of premium necessary when the loss they’re seeking to protect against is 180+ million dollars.
After he was diagnosed with a degenerative disc condition, no insurance company would write Colorado a policy to protect against long term disability of a player who has that large of a guarantee.
It’s a messy situation where the team can require Bryant to submit to exams, imaging, participate in rehab, etc. and he may not want to do that for the next 3 years, so like Strasberg with the Nats and Rendon with the Angels, they’ll likely workout an amended contract and he’ll retire.
