I really don't see another option other than Geno.
However, here's a hypothetical:
I believe that Alex Smith is going to be the major veteran QB acquisition this off-season for teams thinking that they need a guy sooner rather than later or that don't feel that the talent level is available in the draft equal to what Smith offers.
He's got a two years left on a three year deal worth $24 million that has $7.5 million on it for 2013 & 2014. Bonus aren't anything to worry about. It's not a ridiculous contract for a starting QB who was leading the league in completion percentage and QB rating in 2012. He won't stretch the field but he's an accurate short and mid guy who is capable of spreading it around quickly. Good athlete as well.
Would have to be considered as teams that will take a look at Smith.
If the Chiefs went that route, and kept the 34 defensive alignment that they are currently set up to run and they have to keep the pick, my mock would potentially look like this:
1. Dee Milliner, CB; Alabama
2. Justin Hunter, WR; Tennessee
3. Lance Jones, QB; Oklahoma
4. Margus Hunt, DE; SMU
5. Kiko Alonso, ILB; Oregon
6. Michael Williams, TE; Alabama
7. Brad McDougald, S; Kansas
