This was fairly close to the conversation going on between my son and his other senior teammates when I hung out with a few of them last week after his surgery. A few are actually more actively exploring graduate school choices that might allow them to play (and my son already was), but realistically it's a lot more likely, especially for DIII guys, to just move on with their lives.
Some of son's teammates are likely to stay in MN, where townball is a big deal still, so there are also amateur opportunities to keep playing.
