The Rule 5 draft is an event over the off-season that gets a lot of attention, although at times it might get more attention than it deserves. The big concern each year is a "roster crunch", where the Pirates would have too many prospects to protect, and not enough room to protect them. The reality here is that the only guys who are ever at risk of being selected are fringe prospects like Andy Oliver, Nate Adcock, or the rare case with Wei-Chung Wang in 2014 -- taken out of the GCL and straight to the majors by the Brewers, in a move that might have ruined any chance he had at a successful career.
