I wonder if the split is WHY he came back, not the other way around.
If something was going on last spring, then they have a huge fight and decide to split, maybe he was looking at no wife and no football come this fall and just couldn't deal with losing both at once.
IMO he looks different this year, but I just assumed it was to torture me when he suddenly becomes amazing in January and wins yet another Super Bowl when it looked like he was done for real this time.
But aside form the Chiefs game where they just dropped back into a prevent and let him pass to his roster of Pro Bowl WR with little resistance because they were up by so much, he hasn't looked good, and now he has an injured rotator cuff.
