OK, then let's try to identify that RH BP arm we want on a 1 year deal. Start here, and sort by projected WAR:

Plug all the RHP on that list through Melancon with a positive 2021 WAR (a pseudo-random stopping point), and check their xwOBA vs RHH the last 3 years.
Here's the best of the bunch:
Yates, Kirby	.216	
Graveman, Kendall	.249	
Neris, Héctor		.249	
Iglesias, Raisel		.251	
Knebel, Corey		.261	
Jansen, Kenley		.263	
Ottavino, Adam		.266	
GTepera, Ryan		.268
I don't want an $8M flier on Yates, or to spend $7M on Graveman, so give me Neris, Ottavino or Tepera for much less cash.
