Ever since the Saints made Reggie Bush the second pick in the 2006 draft, he has not lived up to the standards set by his great college career. The Saints have a very crowded backfield, with Pierre Thomas, Lynell Hamilton, and Mike Bell in addition to Bush. Bush was the third leading running back on the team, behind Thomas and Bell, and he only had 390 yards. If the Saints release Bush, I think the Steelers should sign him.
There is a good chance the Steelers won't resign "Fast" Willie Parker, who is quickly aging and lost his starting job to Rashard Mendenhall this year. To have the true two man punch the Steelers originally wanted when they drafted Mendenhall, like the Panthers have with Johnathan Stewart and DeAngelo Williams, the Steelers need a new speed back. Bush would be the perfect candidate.
Bush is great at catching passes out of the backfield and would be superb for HB screen passes, something the Steelers didn't do much of this past year. He also could do punt returns in relief of Stefan Logan. Logan was great at kick returns, setting a new Steelers Record in return yards, but fumbled a few times during punt returns.
Reggie Bush could be signed cheaply after a down year, and signing him could be a move with little risk for the Steelers and a huge upside potential.
