Having watched Aaron Rodgers serve as a very presentable temporary host on JEOPARDY and now seeing him with the awful beard and greasy-looking long hair, I think something happened to him mentally.
Supposedly, he was making it known around the time of his JEOPARDY appearance that he hoped to pursue some sort of TV broadcasting or sports commentator role when football was over for him.
In fact, it seemed he thought being a show host could be a stepping stone to a TV career and that he would retire from football to pursue it. Maybe he thought being engaged to an actress would help, too,
Maybe he didn't get any offers and hasn't really enjoyed football since then, which might explain his horrible grooming and bad humor.
How's that for armchair psychology and a lot of dumb speculation? I'll stop now, except to repeat what I say to DH every time I see him on TV......why the heck doesn't Rodgers clean up and find a good barber?
