For me the first I examples that popped into my head were right here in our division. Caglianone, Montgomery, Bazzano, McGonigle. I can't fathom the Twins accelerating a top prospect as quickly as any of those young prospects (guess they're not prospects anymore) Caglianone has struggled some, Montgomery worked through some issues last year and is now a rising star on an exciting Chicago team, McGonigle got a long term contract, and Bazzano has looked like a guy who comes through at the right moment.
It's our turn but the time has to be right.
