On Busch. I will give him .240/.340/.445. So high .700 OPS. His D was solid. So I see that as his floor.
So Happ might be a good comp. Solid player but not a all-star. I would not have given up 2 top 100 for that. But at the time neither were and just because they broke into it doesn't mean that they will become top talented players.
Prospect rankings are a viotile thing. Stud one day and bust the next. Cubs have a long line of this. So trading from fringe (at the time) for semi established is fine.
Like I said, if he busts I really don't care. 1B is a position that you can get a solid turn over for $ spent. Vlad Jr will not command the same as Tucker based off of the value of the position
