From a purely economic consumer standpoint, there's no reason to get season tickets. Tickets are plentiful and cheap all season long, and you can pick which games you want to without over committing.
Personally, most of my UConn Football friends have started families recently and so its much harder for them to consistently get to the games when worrying about nap times, etc. Others have prioritized other things.
There's something to be said for supporting the program, I understand. But purely at an economic value, there isn't really any sense to it.
