Yes good news for sure. I wasn't particularly troubled when DC took over for the injured Koppen in game #2 as Koppen had rated out lower third among starting centers the past few seasons. I'm sure we all remember at least a few instances when he got smashed onto his back, which to me seemed like every other or third game or so. So in a way I was kinda happy the injury forced our hand to try some new players. Although DC wasn't great, almost by default, he was better than Koppen (who, not to read me wrong, I would still take back, only as a reserve. However I expect some bottom dwelling team will outbid us enough and pry him away). Anyway I prefer DC even more now considering the experience he received, how he performed, his positional flexibility and age. I'm sure the Pats viewed him as their primary option for starting C next season, but were playing it close to the vest.
This is a key re-signing IMO.
