Maybe, although I don't think Cook is a great comparison. Cook was a very rigid, robotic, one-speed runner with very little wiggle or agility and inconsistent hands. Pitts is a much, much more fluid athlete and natural receiver.
However I will not be banging this drum because I have seen him take plays off as a blocker which is extremely frustrating but does have the ability in that regard.
What I will say is that we don't ever see athletes of this caliber hit the open market, I don't think Atlanta has been featuring Pitts like they should have been, 13 personnel looks to be the future for this team moving forward, and I think we'll be looking to make a Davante Adams style splash for that last Stafford SB push. Call it more of a soft prediction than what I want to see happen.
