It seems there is a division about whether to go Offense or Defense with the top draft pick. Personally, I believe there is an equal need for an ace WR as well as a 3-4 DE that can attack the QB.
Safety is a need, but not in round 1 if the scouts have done their job. Safety is the easiest position on Defense to fill in the draft and I'm not sold on Pryor or Clinton-Dix. The Chiefs need somebody at FS that is faster than they are, and Alabama DB's haven't panned out as of late ( see Menzie and Arenas and at least 3 others for other teams that I can think of ).
So that would narrow down to Beckham, Lee, or Cooks at WR if they go Offense or Hageman or Tuitt if they go Defense with the top draft pick. With that said, nobody should rule out an O-Lineman because Dorsey/Reid do value these guys & don't let the FA losses fool you because they would have kept Schwartz, if they could have afforded him.
