Great school, strong program. When your rivals are Amherst and Williams, it says something about the quality of academics and athletics.
The NESCAC is a very good Div. III baseball league. Trinity made the Div. III World Series last year. Trinity and Tufts have had players drafted in the last few years, so yes, you can most definitely get seen at one of these schools. Williams and Wesleyan had 2 players in the NECBL last summer. Tufts and Trinity had one each, as well.
the level of play at the top of the NESCAC is similar to the level of play at the low major Div. I level. There isn't as much depth, but the top pitchers and position players at these schools could easily contribute at most Ivy, Patriot, and other Northeast Div. I leagues.
