Degrom looks like extraordinary value - the relievers that jump out at me are Doolittle (slightly better metrics than '11 Mike Adams for the same price) and Ryan Brasier (better version of the 34ip Rich Hill we all love).
I'm not in love with any position guys yet - Juan Soto looks good and my man Ben Zobrist is good value as usual (but hard to put in the field this year). I'm interested to see how Mookie will play out, especially given the success of high-contact '17 Altuve and J Ramirez in the sim, and the trend towards higher k's once again in '18. Andujar is great value if you figure out where to play him!
