I agree with others that it might be too much of a mess to add it. It took a while before you could link players to multiple colleges so just imagine if a player went to multiple schools. I like the idea of lists because it would be a nice way for people to show pride in their schools, but unfortunately, nobody from my school ever went beyond the college level. I do know a couple guys from the next town over who made the minors and have cards and a guy who was in the Saints preseason camp but he never got a card.
My vote if I get one is just use lists. It would be fun when a few are created to see how many came from certain schools. It would also be helpful to see ones from Missouri schools if I ever decide to dedicate more time to my other blog and collection of athletes associated with Missouri.
Royal Card Review is my blog if you feel like checking it out, thanks if you do!- royalcardreview.blogspot.com/
In the process of updating my collection so don't trust any of my lists right now.
