The picks are also spread out, which helps Minnesota. They lose only a 1st this year, and a third and fourth next year. More than likely they will recover one or two picks in the next few years.
Minnesota also has an abundance of low floor, low ceiling type guys and most of their defense is signed for 3+ years.
This is the type of trade you do when you are comfortable with the prospects you have coming into the organization AND don't have enough room to develop them.
In the next few years Minnesota will have Buium, Yurov, Heidt, Lorenz, Kumps, Stramel, Ryder all making the jump. So not a huge loss for them.
Again I don't see a big loss for Minnesota or for Columbus at this point. Minnesota got a massive boom or bust prospect they wouldn't have gotten in the last half of the 1st round. Columbus gets a lot of ammo to continue rebuilding their organization.
