If these are our DBs going into the regular season, I wouldn't be too thrilled with it. If that's who you're going into TC with, yikes! Where do I start?
1) Certainly Spann and Richardson can - and should - be improved on. Can you show me who said that Spann and Richardson couldn't be improved upon? They certainly can, but there is such a thing as a salary cap. And it limits you to how many "starting quality" players you can have on your team
2) Hopefully, Sanders can be improved on as well. At least from a coverage perspective. This is where Springs would become a Safety.
3) Springs at safety? Not sure. Did you miss the Springs interview where he said that safety is basically the position he played last year, though he lined up in different spots? I think that is one of the reasons the Pats signed him.
4) Who's going to play in the slot? This was a huge weakness last year. My guess is that they could bring Sanders off the field and put Wheatley in the slot.
5) There's no guarantee that both Bodden and Springs are going to work out - one of them could be the next Fernando Bryant or Duane Starks. Well, while Starks didn't have success, much of it was due to injuries. Bryant was paid very little money in comparison to Springs and Bodden. Its much more likely these two will play.
6) Two words - injuries, competition. Yep. It happens every year.
7) Even if everything works out, Hobbs and Bodden are FAs next year and Springs will be 35. As things stand right now, with next year being uncapped, both Bodden and Hobbs would be RFAs, not UFAs, as neither would have 6 seasons in the league.
8) This doesn't even consider the question of whether a mid 2nd round pick this year would be a better prospect than Wheatley and Wilhite.
So I would say that CB is still a need. And Safety is still very much a need.
