It's a legitimate question at this point. He has the team's highest BABIP, 2nd worst K/9 ratio, 2nd most home runs allowed and worst ERA.
However his xFIP and SIERA are actually very good, which I think supports what most on here have been saying i.e. that his whole "pitch to contact" approach is s***ing the bed big time and given his talent utterly unnecessary.
He needs to go and reinvent himself; a few extra days rest are not changing this problem.
