I don't want Machado as SS and Franco/Bohm at 3B the next five years, while defense may be overrated, that's really a bad combination in a game that is heavily RH. I think Machado has peaked, and what you see is all you're gonna get as a hitter, while he'll go downhill at SS quickly as his range steadily deteriorates. So while he'd be value at 3B, he'll be a gross overpay at SS.
I'd rather resign Ramos for a 2-3 year deal and gradually work in Alfaro, who is a long way from being a reliable ML hitter.
I'd sign Harper if his market collapses, he's fine value at $20-25M for 3-5 years, just not a megadeal.
I'd keep Bour and overpay him to eventually phase out Santana next year, and Hoskins can start playing 1B against LH to eventually move there when we sign Trout in 2021. But I'm not stripping the farm system for one year of his play.
I'd re-up Hernandez and buy time for Kingery, Crawford and all the LA IFs climbing the system ladder.
I'm not giving big money to a RP unless he's exceptional and in his prime, not based on past performance at a position notorious for players falling off the cliff. Keep stockpiling young arms and rotate them in, you need 8-9 RPs in any season.
