TOP 400 UPDATE
Before getting to the outfield prospect tiers for dynasty leagues, I wanted to touch briefly on last week's update to the top 400 prospect rankings.
The majority of the movement was to the back half of the rankings and it reflected all the work I did with the divisional prospect articles, in which I wrote about 750 total prospects. I think the biggest theme from this update was that I wanted to stress upside in that 200-400 range. Of course, I stress upside throughout the whole top 400, but when I roster prospects in dynasty leagues, I'm only chasing upside in those final prospect spots. This means that the likely No. 4/5 starters got bumped off the list in favor of teenagers who may never amount to anything. You should be churning your last few prospect spots pretty regularly. I'd rather roster a guy like Estiven Machado or Richi Gonzalez and then cut them in July if they're not hitting than roster a starting pitcher for several years who is likely to pitch in a big-league rotation, but is unlikely to ever be a player who is sought after in mixed leagues. Even in 20-team dynasty leagues, you can often pick up a David Bote or John Means off waivers, so why roster the prospect version of that player?
It's also important to stress where the tiers are in the top 400. The gap between a player I have at No. 3 (Julio Rodriguez)
