ELI5: what makes people so attached to college sports teams when the actual teams themselves are barely the same from year to year?

I mean, I get sports, I am a huge mlb and nfl fan. I live getting sucked up in my teams "story". But I don't get college sports. Anybody exciting is only with a team 1, maybe 2, years. It's like minor league baseball, which is not really that popular beyond the local level. 

What gives?

Most people are fans of the school they went too.  In that case the "connection" is that they attended college there... and then continued to follow the team after they graduated there.

Other teams carry massive regional appeal (the University of Alabama is a prime example) ... which is also often linked to a lack of a professional team attached to that area.
