Just to pile on the it would be silly to trade Brown side of things, seems like the current Cubs regime has a pretty solid track record of producing MLB competent position players and less success on the pitching side, especially starters. Seems like hanging onto one of the few guys they've managed to get over the development hump would be prudent, assuming they think this injury is something he can get past, and trading from the excess makes way more sense, especially when it seems they have some more guys in the pipeline to backfill already.
