If you look at the CBS revised rankings, and you want OL, the first round in the low 20's is full of talent we could use:
20 Anthony Davis OT
21 Sergio Kindle OLB
22 Mike Lupati OG
23 Brandon Graham OLB
24 Bryan Bulaga OT
25 Dan Williams DT
27 Bruce Campbell OT
Trade down from 13 to 22 is worth 370 pts, which equals pick #53.
49 Terrence Cody DT
52 Jerry Hughes OLB
54 Perrish Cox CB
58 Jon Asamoah OG
17 Anthony Davis OT or Earl Thomas FS, or whomever falls if there is a run on OTs?
22 Mike Lupati OG or Bryan Bulaga OT, or Bruce Campbell OT
45 Brandon Spikes ILB, Chad Jones, SS, Charles Brown OT, Terrence Cody DT,
53 Jerry Hughes OLB, Perrish Cox CB, Jon Asamoah G
If there is an early run on OTs, (usually is) take a tackle at 17. If there are still a few on the board, take an OT at 22 and see who falls to 17.
By trading down, we can get a good OT, and either Lupati or Asamoah at OG, and two potential game changers: Golden Tate WR, Thomas FS, Perrish Cox, CB, Jerry Hughes OLB, Brandon Spikes ILB, or Mount Cody for NT.
