Same place you got your idea that Adams might be of some use.
You don't know what JS and Mac see as a viable option any more than I do. I'm sure that they consider a lot of things, from the practical to the absurd.
Like all NFL GM's and HC's, JS and Mac are going to say the politically correct thing when they're in front of the microphone, especially this time of year when we're a few weeks ahead of the draft. Like Mike Holmgren once said: Everyone lies.
Until there's an announcement that they're actually bringing Adams back, this proposition is nothing than mere speculation.
