According to Jason Cole of Yahoo! Sports, part of the package that they’ll be offering Bush is the chance to be their starting running back ahead of Mikel Leshoure. That would seem to be significant for a player who proved in Miami that he could handle a more rigorous workload than he had in New Orleans, especially with some of the other teams perceived to be bidding for his services unable to offer the same kind of playing time.
The Redskins have Alfred Morris and the Bengals have BenJarvus Green-Ellis, players who would at least split time with Bush and might even push him into more of a passing down role. Bruce Arians has talked up Ryan Williams in Arizona, although it’s less clear how things would shake out since we’ve seen so little of Williams during his first two professional seasons.
The Cardinals have quarterback issues that none of the other three teams have, however, and that would likely be on Bush’s mind before choosing his next destination.
