And that could become the problem. If they have Mize, Skubal, Manning, Torkelson, and Greene hitting their primes, they're going to want to keep what they can and they'll have a declining value contract in Correa on the books (if he's still healthy, let's not forget that part of his resume).
It's wise to construct a contract that way, a bell shaped curve that offers some financial protection. But if a contract has a base value that high, even bell curving it makes it awfully risky.
