I disagree a bit with what was said earlier. First, in terms of punts, I do agree in that I do think teams will try and punt away from him, but when he gets his hands on them and gets a seam, no one can catch him, because it wasn't even close when that happened last year. Thus, I don't think he'll get as many returns, or yards, but I still think he can bring 3-5 back for the score over the course of 11 games, and his impact on field position will still be consistently felt even if he doesn't get his hands on it as much. So, I think he can score as many (roughly) and still have as big an impact, if not the yards.
As for adding plays specifically for him, I'm sure I'm in the significant minority, but I hope they don't do this much, but incorporate him more in the base offense. It seems that in a lot of cases, if teams come out thinking they "have to get the ball to player A no matter what" that they press it too much, and end up getting out of what they're trying to do schematically. So, tossing in the occasional end-around or direct snap for him is great, but I'd rather see him as the go-to guy in the slot or even split wide on more plays so that he can naturally work into the offense with all of our other weapons, forcing the defense to consistently respect his presence and freeing up our other guys in the flow of the offense. Just my opinion.
