Today's game require year-round engagment. I remember buying a pre-season magazine, at the start of every season, and catching up with what happened in the offseason (incoming recruits, transfers, etc).
Today, I don't think we could fit all that in a few hundred pages.
I love the freedom today's player has. As a former collegiate athlete, I remember being at the mercy of my position coach and HC. I love watching a player exercise that freedom to make the best choice for them, in their opinion. It's concerning just how many freshman have entered the portal, but, like all other industries, I'm sure it will settle with time.
I do love the diversity of scheme, in today's game. Years ago, everyone lined up with a fullback and tried to beat you with Time of possession, and limited turnovers. Today, you see a mish mash of schemes that would of been seen as crazy decades ago. Everyone has their own version of the 'air-raid'. This is what I love the most about today's game. If your bored on a Saturday, just turn on a FCS game and see what coming (schemematically) in a few years.
