I think Peterson is showing that he can be a good middle-of-the-rotation guy going forward. If they can reasonably work out the Stroman and Syndergaard situations, I really like the idea of deGrom, Stroman, Syndergaard, Peterson, 5th guy moving forward. That being said, I'm obviously banking a bunch on Syndergaard getting fully healthy and Stroman being signed to a reasonable deal.
I think they have good enough pieces to make a big swing for a pitcher if they wanted to, but I'd be really uncomfortable making that move at the moment.
