Need some opinions on what I should write my sports book on? (Might be a tad long, don't worry)?

I normally don't ask questions on here, but when I do I like to help people on here.

My question is this:

What should I write my sports book on? I'm thinking of doing college basketball or college baseball

I feel I should college basketball because I know more about it and the teams I'm thinking about writing are: UConn Huskies, Virginia Cavaliers, Illinois Fighting Illini, and UCLA Bruins, it's mainly going to talk about how these programs are today and were in the past.

The college baseball book, is basically the same, except the teams are different. I'm just confused on which one I should write about.

Thanks for those that help me. :)
