I voted TJ Watt based off of the list you provided...Although (as in my top 5 above) I would rather go Willis or Bowser. Both are physical freaks and display good tools. Obviously, they are not complete players, but if you are looking for an edge player at 22, you can either go with a Physical freak that needs a little coaching or a guy with good tools but lacks the athleticism.
If you are hoping to land a very good pass rusher in the back end of round one, this is the draft to do it. I like Lamp and Peppers, but you don't pass up on an edge guy who would project in the top 15 in most drafts if he is there at 22...just like the fins were smart to not pass on a top 3 player in Tunsil last year.
