Right there is the key conundrum. IF we can upgrade. Half the teams in the league are hoping and praying to find a tackle, or two. There are reasons why every player out there still available are indeed still available. And there are reasons why nobody would be in the market to trade away perhaps the rarest commodity in the NFL today, the competent tackle. I would, of course, love to find an upgrade at every o-line position as would, I imagine, the Saints front office and coaching staff. This is much, much easier said than done it appears. I doubt they are "sitting on their hands" when the probable fact is that their hands are tied for one reason or another.
