Because they have Vrabel, they have a lot of options with how they address the LB situation. So I really don't think Curry should be the pick.
At #3, they'll be able to trade down within the Top 10. Someone is going to want to move up to get one of the guys that will be there at #3 (Curry, Stafford, OT, Orakpo, Raji). The Chiefs are in good shape. They'll pick up extra picks, not move down much, and probably be in a position to move down again if they want to.
If they do use the #3 or a Top 10, I've grown more and more on the idea of taking an OT. I think it's the biggest impact they can make on the team in the first round. Moving Albert to LG, and forming a dominant left side with either Monroe or Oher would do wonders for the Chiefs' offense.
If they have Vrabel play Mike, they have 7 rounds to find good rush LB's and ends (draft is loaded with them), and there are a lot of fun options at WR and TE (and RT if need-be). But this draft is weak at G, which might be a big need for the Chiefs.
I'd like to see them get an Eric Wood with the extra high pick they'd get in a trade-down. If they traded with the Browns or Bengals, they'd be in position for Oher.
