39. Tyler Anderson (Rockies career WAR: 6.4)
I have heard many who wondered why Tyler was “allowed” chance, after chance. Little do they realize he has only pitched in 4 big league seasons.
Starting with a promising rookie campaign where he chucked it to the tune of a 3.54 ERA in 114.1 IP for an ERA+ of 137 in 2016. Only one season was below-average in any measurable way. Unfortunately, he is just one of many promising arms that have for one reason or another been beset by numerous injuries that have sapped a lot of that talent.
He was, however, still good enough to rank in the top-20 in Rockies Career Pitcher WAR in that short time. I would say he earned every opportunity.
