For the Falcons, the biggest want is Clowney. I'm not entirely convinced he will fall to six, so other guys that have caught my eye are Khalil Mack, Greg Robinson, or if they choose to trade down Aaron Donald or Rashede Hageman.
Right now, the number one pick SHOULD be Clowney based on pure talent. However, Houston has bigger needs, you know QB. Because of this, I'm gonna go out on a limb with a bold prediction and say they make a lot of the longer-tenures fans upset and take Derek Carr.
