The Royals will still suck when all their prospects reach the majors, if that ever even happens. If they get one star player and 4 other average major leaguer starters (like top 15 or so for position players), they'll have done well with their 10 prospects. That's still only 5 players. Where are the rest going to come from? We've seen with the Nats how hard it is to get quality free agents to come here.
