He's better than our 3-4-5 guys from last years rotation! His 4.21 ERA would have lowered our team average from last year! Gotta have a little faith
No, he's not better. Just as bad I think. The guy has been a below replacement player his last 3 years and over his entire career. That 4.21 ERA in the NL will on a team with average to above average D will bloat to >4.5 ERA in AL and with the Twins D in all likelihood. I hope you are right and I am wrong.
