how did zac gallen go from finishing 3rd in cy young voting to the worst qualified starting in baseball? 

a few casts on gallen's field independent pitching (fip) vs. expected era (xera), declining command, and opposite side struggles

This type of content would KILL on baseball Twitter if it were discoverable. 

I so wish FC had more people that cared about baseball so they could appreciate this.
