Suh doesn't fall that far.

If he ended up at 5, KC will look to either trade down (I'm sure a few teams would be looking to jump up for oneof the top 3 players in this class) or take him themselves. He could play end and they could move Dorsey over the draft weekend. Maybe they try him as a 1 Gap or 2 Gap nose or they could move back to a 4-3 which in not totally inconceivable either given having a player of Suh's talent level falling into there lap.

If Suh got by KC, Seattle and Oakland both don't pass on him and Cleveland is another team who takes him and plays him as a 3-4 end.
