If Hamels and Quintana's contracts come off the books, that is two starting rotation spots they have to fill with zero likely internal options. If Strop's contract comes off the books, that's a huge bullpen arm they have to fill with a new reliever, again likely with zero internal options. They aren't declining Rizzo's options. Their pitching prospects are terrible. And while the rotations is theoretically set, it is old and will be in need of external acquisitions, which will cost money or prospects, and they don't have prospects. The 2020/2021 pitching staff is a mess and is going to cost a lot of money to fix. I agree with Hamels, Quintana, and Strop costing big money to replace because of our crappy pitching prospects, but you still need bodies to replace Morrow, Chishek, and Kintzler too. That's 2 starters, a closer, a set-up guy, a decent reliever, and a replaceable arm. Unless Harper/Machado are planning to be two way players like Ohtani, I'm not sure we can afford them.
