I was just looking through the Jays' minor league rosters and look at this:
c: G. Quiros, K. Cash (Quiros the c of the future)
ss: Russ Adams
OF: Rios (a top 3 prospect in all of bb), Jayson Werth, Gabe Gross, John-ford Griffin
P: Dustin McGowan (a top 5 pitching prospect), Jason Arnold, Brandon League, Vince Perkins, David Bush
Those are all good prospects, at least 5 of them are sure fire major leaguers.
Add to this the young ones already in the majors: Hinske, V. Wells, Halladay, Phelps, Hudson.
