That's a lot of assets (money AND high draft capital) to spend upgrading the secondary when there are huge holes at OL, WR, and they only have one professional TE on the roster now. I don't disagree though, that's a GREAT group if they can swing it AND get the rest of the holes filled.
I have a feeling that this off-season will be about loading up at some spots while leaving others bare...e.g. I don't expect us to upgrade massively at WR because of what is available out there....but I think we will spend money to re-tool the defense to be sure it is still STACKED with talent.
