Last year, Nola posted a 3.59 ERA over 77.2 innings in 13 games. That 3.59 ERA was better than 70% of NL starters (and best on the Phillies) with at least 70 innings pitched. Now, to be a top-of-the-rotation pitcher for a competitive team–which the Phillies are hoping to be in a few years, you have to be better than above average. I understand that. But he’s 22. It wouldn’t be a bad idea to get him some experience as The Guy™.
On the flip side, if the Phillies elect to give him the top spot in the rotation after being slightly above average in 2015, maybe that would actually hurt his development. Now, I don’t take Nola to be a guy that’ll stop working his butt off once he gets a career achievement, but I always look at things with an open mind. I can’t exactly rule a scenario like that out.
