I think fans who were really into recruiting as part of their year college football addiction are feeling a little bit of a "hole" in the calendar. With the Internet a cottage industry was born around recruiting - Rivals, Scout, etc. - and it grew to be a force in the world of college football. Keeping fans attention during the off season similar to the NFL draft. Drama was created around who did we offer, who is visiting, who has put us on their final list.
It would appear much of that has been lost with the increased emphasis on the transfer portal so I believe some fans who really enjoyed following recruiting feel like something is missing.
You can say you only care about the games and what happens on the field but that is not all that College Football is about. There is obviously a lot of turmoil in college athletics and it will impact fans perspective.
I'm one who never really was invested into recruiting pre-internet and remained that way during the internet days.
Not having that annual college football videogame since 2013 left a hole in me and that is about to be filled back up. Thankfully that is coming back and will fill a huge gap in my offseasons from football.
