Players don’t stay with teams forever, but inter-division trades aren’t the standard in the NFL... which is a shame, because there are some amazing running backs in the NFC East that I typically hate on Sundays, but envy just a little bit.
Trades and signings within a division don’t happen all that often, and when they do, they typically have a bit of a bad break-up vibe — think Donovan McNabb and DeSean Jackson to Washington. Sure, sometimes it’s purely a business decision, but going to your former team’s division rival is definitely a little more personal than, say, going from the NFC to the AFC.
