I wonder why he would stay to begin with. I mean how many years does D Will have left? Wouldn't he want to be the feature back. But maybe for once a player realized that he could win a title with the current team he is on. He put the team above his ego. Congrats to him.
Both he and DeAngelo have stated that they enjoy sharing carries with each other, because it'll improve the longevity of their careers. They're a fantastic duo, and I'm glad to have them both locked up. It's clear they both see that this team has the potential to be something very special, and they want to be a part of it.
As for DeAngelo's deal, he has no guaranteed money left after this season, so they could either restructure his deal or cut him. I could pretty much guarantee he'll stay, though.
Good for them both. They could easily be star running backs in the league if they had their own team and got all the carries. But they realize that the two of them together could get them a SB ring and thats really saying something in today's day and age....because people dont stay on their current team very much anymore.
