6/90 seems like a pretty big reduction in one free agent price, and the fact that players are returning to Japan seems to reinforce that the FA prices are indeed largely reduced. Your argument makes no sense. You are literally providing examples that disprove your theory.
I think someone will pony up, and I don't think it'll be us. The question is more whether it'll be a one year deal or a long-term one. The other question is what exactly IS Bauer. Is he an ace, or a durable #2/#3? He's been all of those things over the last four years.
Honestly, I don't think I'd mind all three of them at those prices. Ryu, Pearson, Kluber, Paxton, Tanaka would be a pretty amazing rotation. Risky, but amazing.
