Okay, then let's look at this past offseason where Seattle let 29 year old Red Bryant walk and signed 34 year old DT Kevin Williams.
I do agree with you that draft picks are important. I've said many times a team cannot afford it's star players without having some rookie contracts to offset the larger ones. IMO when you make those FA moves they have to be value focused unless you see a franchise type guy available. Looking at the above move they would have kept Bryant, but the price was too high and they opted to spend less on the older player. Those are the smart FA type signings that help.
This trade is interesting. Is Willis stil playing at a probowl level? If you medical staff completely checks his toe, then he's a guy that made every probowl until this past year where he missed 10 games. I completely know he's almost at the twilight of his career, but for a team that lacks leaders on that side of the ball the reward outweighs the risk. Add in that he'll be another coach on the field for what Vic is trying to do and there are intangibles that really make the move worth while.
