I was, and still am, a supporter of an offensive first catcher, I'm just not sure Sisco's offensive is good enough to make up for the glove. It worries me that he seems to start every season strong and then his numbers go into a steady decline.
With Severino it's that he's looked downright lazy behind the plate the last couple of seasons. I don't care if you run out every ground ball but you need to get down and smother pitches in the dirt for your pitcher.
