I don't think it was just PR by the Saints. They wanted him back, but only at their number. There was no way they could pay him the $5 mil per year the Dolphins are willing to pay because that would be more than Pierre Thomas, Ingram, Ivory, Colston, etc., etc. are getting. A $5 million contract for Bush would have inflated all their future deals and/or annoyed players who produced more than he does. If Bush would have agreed to an incentive laden deal worth around $2.5 to $3 million per year, he would still be a Saint.
