I think the league dynamics are a reflection of the experience on each of the top 6 teams. Ithaca starts 4 seniors which include 3 5th years and a 4th as a first option off the bench Hobart starts 3 seniors which includes a 5th year player in Jackson Meshanic. A fully healthy Vassar starts 5 seniors, they are currently starting 4 seniors and a junior. Skidmore starts 4 seniors which includes a 5th year in Skoric. RPI starts 4 seniors and a junior which includes 5th year Dom Black. SLU is the youngest of the group, normally starting 2 sophomores, 2 seniors (no 5th years) and a back and forth starting option between a senior and 2 other sophomores. It's no surprise that all these teams at the top have the records they do with the experience they have.
I have been wrong many times before, but I think next year there will be a "reset" of sorts across the country. What I just described applies to most, if not all of the top teams this season. That's not unique to this season, but with the vast majority of impact covid year players getting cycled out after this season I get the feeling d3 hoops will be a different landscape next year.
