I am rewatching as many of last year's games as possible. A surprising number of full NFL games are available on Youtube, sometimes in condensed form. So far I have watched about half of 2018.
Now I may have just hit bad luck, but in nearly every game I have watched Jo Jo has made a boneheaded decision that lost us yards or on one occasion, lost us the ball. He starts by running backwards too much, and in the games I watched rarely broke anything of substance. In the games I saw, he would have had a higher net average by taking the touchback whenever available and fair catching every punt.
Memory tells me he had some notable returns last year, but in what I watched he was a real liability. I hope that is a high priority for improvement this year. It is the only real blotch on our ST.
