If they hit years 4, 5, 6 and are not optioned back and forth (I will ignore injuries as that has nothing to do with talent) they are Major League quality.
Years 1,2,3 are a crap shoot.
The Twins are in a position to attract fans and money, as they have last years record to build on.
This is NOT the time to be an extention of AAA, a veteran , even one who is not what he once was, knows the game and that is the part rookies do not have and it shows in their play.
Lewis, Castro, and I will here will even say Wallner seem to be firing on all cylinders, showing they are probably going to be in the Majors for a long time, in probably one place many of the years.
Larnach, Kirilloff, Julien and even Jeffers are running like a hit-miss engine.
