I would be ecstatic to bring Winfield aboard but he would have to want championship over money for such a deal to happen. I've read that he is asking for somewhere around 7 mil (per year!) and I don't see JS offering that. Unless he's squandered his years of NFL money, he should be equally happy with 5 mil and a ring, IMO.
It's no wonder he is scheduled to visit the Skins. Only Snyder (and Jerry Jones) throw money around as recklessly as that.
