Not much I disagree with there, except for two things.
For one, I'm a little more positive on JP. I don't think he has that special something that Kelly had, but I also don't think that's a requirement...to be a successful QB, or to win a Super Bowl. I do think that JP has some great tools. I was impressed at how he was firing the ball in that last game despite the wind, and still getting good velocity and accuracy (for the most part). Once he settles down some and gets the hang of some of the finer details, I think he'll be a very good QB, particularly given his arm strength and mobility.
For another, I do think TKO can come back and be with the team for a little while. The thing that impressed me in the NE game is that he got on Brady in a big hurry to make the sack. No speed problem there. And this was his first game back from the injury. As has been said before, TKO at [some number less than 100%] is better than most LBs at 100%. I don't know what the cutoff is for that number less than 100%, but until I see more I don't think he'll be a liability in any way.
