Depends on your definition. The Twins have a good collection of guys who should contribute as major leaguers in the upper levels - high floor sort of guys that should work on a major league bench at least like LaMonte Wade, Mitch Garver (technically not officially graduated as a prospect), Zach Granite, Gordon, and one that a lot of people forget about, Max Murphy, one of the better defensive outfielders in the entire farm system. T.J. White and Chris Paul could also be guys who wouldn't be stars, but could be at least solid bench pieces if not decent regulars. While that's not flashy, that's significant to have that many legit major league caliber players in the upper minors. There is a reason many around the game have really stood up to take note of the Twins system depth from top to bottom, not just the high-variance talent in the lower levels, but the guys who are at the upper levels as well.
