You have to start with the Yankees, the really smart science nerd that doesn't have to study to get an A. Follow that with the smart ass that constantly tries to one up Edwin, and ends up looking like a fool: The Red Sox. The next student is the really smart kid that has it all, but doesn't seem to care: The Mets and Dodgers. Everybody loves the smart and social guy that will help you with your homework and has the respect of everyone: The Rangers and Braves. Then the kid that everybody tries to console, he knows the material but always stresses out and bombs the tests: The Cubs. You can't leave out the hard working students that work 30 hours a week and still find time to study: The Twins and A's, and currently the Rays. Don't forget the people that constantly ask to copy your homework and write notes on their hand on test day, the Steriod Era players (that one was too easy).
The Royals analogy is based on the Dayton Moore era: At the start of the semester Luke worked harder than anybody else. He was on student loans and knew he had to study and work harder than the others: The Royals development of the best farm system. After the first couple of tests Luke became content, didn't study as much as he should of, and even skipped a few classes which dropped his grade to a C: The Royals recent drafts, and offseason moves. Jimmy cannot become lazy, he has to step it up, put in the extra time to earn scholarships and awards.
The Royals have become content. I think that Dayton Moore believed the talent in the minors would be enough to succeed. I would be very surprised if the pitching staff they have built will be good enough. They are sending out average minor league pitchers 3 out of 5 days. Yes they have had injuries this year but shouldn't "the best farm system ever" be able to send out promising pitchers? I realize pitching is hard to develop but it's not impossible. The Royals farm system has produced only one starting pitcher, Danny Duffy. He looks promising, but you never know how a pitcher will respond to Tommy John surgery. With Dayton Moore unwilling to trade promising prospects for big league pitching, and the Glass family against spending any money, they may have to drop out.
