Cardinals in on Alex Smith bidding?

In the Arizona Cardinals' quest to field a more competitive team in 2013, they've set about trying to adjust their stable of QBs. Part of the process is assessing what they have on hand -- Kevin Kolb, John Skelton, Ryan Lindley and Brian Hoyer were on the roster by season's end, though Hoyer is headed back to free agency -- and there has been some talk that Kolb will be asked to re-structure his contract (translation: take a pay cut). But they're also expected to target some outside options via the draft, free agency and/or a trade, and there's new evidence that the team may get in on the bidding for 49ers backup QB Alex Smith.
