OK my turn, as I got some inside poop on this no jacket issue. The jacket was not left in the locker room. It did make to the floor before the game started. Not sure if JL brought it out or someone else. How I know is that Mrs JL got out of her seat ( while the team was getting their last instructions) and I believe picked the coat off the floor behind one of the first teams chairs and walked down to the end of the bench and folded it to her liken, then put it over one of the end chairs. Someone then took it to the locker room at the half.
Now as to WHY he did not have it on the first half, how the hell would I know:!:
