Prospects to sign/draft in the offseason?

No specific order...All are of importance:

FS-(Earl Thomas)...Make an argument that Marcus Williams/Coleman/Bell duo is a good enough safety rotation in pass coverage.
DT-Gerald McCoy (if released)...Onyemata and Davison are exceptional rotational players. Capable of starting. However, a dominant all-pro like McCoy can make a difference even though he's been getting older. I've seen one too many times where we can't get any pressure from rushing just the front 4.
TE-Jimmy Graham (if released) or another TE. WE NEED A TE.
LB-another LB for depth/upgrade over Klein
DE-another DE for depth. Can't get enough of pass rushers.
CB-If PRob isn't on the roster, then we need someone who can cover the slot.
O-line-another G or T for depth. Can't get enough O-line help.

I've listed 7 positions here that I believe should be upgraded or added for depth. Please go through each one and tell me whether or not you agree and why. I didn't list the WR position here as a position to focus on because I think Thomas/Ginn/Bryant tandem is a good group. However, you can also make an argument to upgrade the #2 WR position.
