Not meant to be a diss, but can you do an interview with someone that's a "Fan Favorite" and not just "Random Dude Who Was Available and Tracked Down"? No offense, but Marc Hill was never that spectacular of a player on either side of the plate, whereas Karkovice was a great defensive catcher who played on some good teams in the 90s and might be an interesting read.
Joe Crede would be a good get. Rudy Law might be kinda fun. James Baldwin would be pretty funny. Just some suggestions...
