I'm curious if it's common for coaches to delay the final decision about greyshirting until spring. Former teammate of 2013 is on the expanded fall roster of a very competitive D3, but conference limits the roster number for the official season. This player is hearing from others that sometimes coach keeps the extra players into spring and then asks several to greyshirt just before the season begins.
I would think coach is waiting to see how the freshmen in particular do in their first semester of grades (may lose some just by attrition), as well as their dedication to off season lifting, etc.
