Not trying to crap on your thread/exercise idea, but:
Without Harper/Machado, there is no $150m payroll 2019 plan that makes sense.
Even with one of the big two, we’re still rebuilding. No combination of free agents and trades can make a $150m team that’s any better than the one that failed us hard enough that it caused a rebuild a couple years ago.
Yes, you can envision a dream scenario where every player takes a step or two forward and no one gets injured and the club decided to get four premium free agents, but the likelihood of that happening is akin to playing the lottery, except the cost of the losing lottery ticket is five years of shitty baseball instead of two bucks.
