See, I disagree with this. I agreed that it wasn't worth Newman, but Newman was never the returner that Pacman is. Pacman is a Hester-like punt returning, he's dangerous as hell, and will often make the opponent shank the ball out of bounds.
You put him back there. He's young and we're deep at CB. Did we not let Deion return punts to worry about risking injury? Ha, we even had the guy playing offense. You might see the same thing from Pacman once he gets into the flow of things, a couple trick offensive plays. It was mentioned awhile ago but no one has said anything about it lately, so we'll see.
Either way, I don't think you can take away that large of an asset to your team. If we're up in a blowout, sure, throw someone else back there. But don't be mistaken, Pacman is a game changer.
