If the Steelers and Patriots were companies, the Patriots would be accused of raiding. How do you hand your rival someone as knowledgeable as James Harrison? Even If he never plays a down for New England, what he brings in terms of what he knows about his former team is huge. Do you really want to give Bill Belichick that kind of edge?
