Actually lately I had been leaning towards the idea of keeping Williams, try to sign him long term.
After today, with Raiders DT Tommy Kelly getting a 7 year - 50 million (18 million guaranteed) deal, I've started to lean towards the idea of trading Williams and getting what you can for him.
That's massive money, and I can't (and don't want to) see the Packers giving Williams anything near that amount of cash. Not at a position we are so deep at and rely on a rotation.
With Cole reportedly getting the second round RFA tender, I can see Ted looking to actively pursue a trade for Williams. Problem is that Rogers, Jenkins, Stroud are also rumoured to be on the market, so the supply of DTs available might be greater than the demand, meaning the Packers will have to settle for a lower draft pick than they'd have originally wanted.
