The point is until he repeats 2017, no matter how he did it, no matter how good he looked doing it, no matter how convincingly he did it, it's a one-off season. Add onto that the unknowns of his injury (and even though it looks better than a lot of other shoulder injuries, there are still unknowns) and you have not only a classic outlier season, but additional worries about him being able to repeat it. Baseball is littered with players who, for a whole lot of different reasons including injury, had seasons which were not typical of the rest of their career. Some of the more memorable ones for me are: Roger Maris (1961) Mark Fidrych (1976) Pat Listach ( 1992) Brady Anderson (1996) Jeff Francoeur (2006) Daisuke Matsuzaka (2008) Some of those guys had nice careers, some not so nice, but none of them were the player they were in their peak year at any other time in their career. I am sure at the time they had their peak seasons the was plenty of talk about their future being bright, but they were outliers never to be seen again. Until Nelson repeats his 2017 season, or betters it, it is the dictionary definition of an outlier. That doesn't mean it will always be, and it doesn't mean Nelson can't be a top-of-the-rotation starter, it just means he has to prove it. I’m telling jimmy you guys think his 2017 season an “outlier”.
