M2 actually got me thinking about this when he mentioned BJ Upton in the all breakout team.
So here are the rules you get to pick one team. You can use players from both leagues. The player needs to be on the cusp of breaking into the majors, in other words, no Jay Bruces. The player must be eligible for ROY. Guys like Hughes and Bailey are acceptabe except for one final rule... You cannot pick any Reds farmhands.
Again pick a player for each position, 1 LHP and one RHP. omit relievers and closers, unless you really want to add one.
