In the NL.
That is one of my biggest issues with Snell. Even in his prime in 2006 and 2007, he was 4-4.20 true ERA pitcher in the NL (with terrible LH splits) which translates to something in the mid to late 4s in the AL.
Hes never had an FIP below 4, his only career tRA below 5 was in '07, and his lowest xFIP was in 2006 at 3.99.
If he gets back to that level, hes more innings eater than impact arm.
Theres nothing wrong that. If he can become a solid MOR/BOR type, that trade would have been a success. He got some things to fix before he gets there though.
