He is getting better every year and if we can keep him on the field next season, it would only make our secondary that much better. We can't give up on him and then go draft a guy with no experience.
I 100% disagree with you, 2 years ago he had a good season, last year he was bad when on the field, and this year he has been worse when on the field. Go To nfl.com and watch some highlights, after the other team throws a long bomb for a touchdown, watch right after the play, #20 will come into view, late on the coverage. He is one of the worst coverage safeties in the league, He is a liability, and now that he is getting older he has lost his sting on his hits, and doesn't seems to want to hit players anymore like he used to. We don't need to draft anyone to replace him, we already did, Morgan Burnett was looking like he was already better than bigby in his rookie season, but he also might have nagging injury problems now. So I wouldn't be opposed to drafting another Safety, as that is a very important position in the 3-4 scheme of capers.
Either Way Bigby has got to go, he looks like an old man out there.
