Re: Dansby and Bell, these are going to be big decisions but for different reasons.
The issue with Dansby is cost, production and use. Dansby was paid 2.5 mil in 2013 and received 100% of the defensive snaps. Not only that, but Dansby was very productive in those snaps which increase his value. You could argue Paris Lenon totalled a number of stats but his actual production was minimal.
The obvious concern with re-signing Dansby is age. How many more years are you willing to pay for his 2013 production and how much will that production decrease over that time? IMO, Dansby has 2 to 3 more productive years playing next to a player like Washington. Washington helps mask Dansby's decrease in athleticism and puts him in more situations to be successful.
A pay increase will have to happen, but I personally would be comfortable letting the market dictate that increase. I believe 5mil per year would not be terrible, but I believe the market is one that could set his price below that. Roster's are flooded with ILB talent across the NFL and that is one of the reasons Dansby was released and had for the price he was. That isn't to say he isn't a player teams will pursue, but they will take a much harder look at his Dolphin's years than we will when it comes to paying him going forward. Also, I believe Dansby like his situation in Arizona. It won't get us a discount, but I do believe it will give us the chance to match any offer he receives.
Regarding Bell, you have a similar situation except the cost risk is down as is the actual production. Bell played 99% of defensive snaps in 2013 but was not a real productive player. He is good vs the run in the box, but struggled in coverage and limits the overall versatility of the scheme because of this. Teams we able to manipulate the Cardinals defense in ways to put him in situations where his coverage skills could be exploited. Bell can be had back pretty easily by the Cardinals mainly because he won't cost much. The question the Cardinals face is do you spend in FA to replace his production which will be an increase in cost and probably an increase in production or do you wait and fill the spot in the draft, lowering the cost, but also increasing the chance of a limited increase in production. That is my mind is the tougher question.
If it is me, I would sign a more talented S in FA. It will be a significant cost increase, but not as much as a CB, OLB, OT, QB DE would cost. Signing a FA S gives more flexability with our early draft picks and puts us in a better situation to draft a more premium position early.
