One of the mainstays of offseason articles is to create rankings and lists of top players in the minors. My annual top 50 piece will be published by the end of the week, likely on Friday. David Groveman is working on his, which will be posted before the start of the minor league season. And of course, all of the other sites big and small do this, too. With prospects on everyone’s mind, this is the perfect time for an email exchange with David.
