Should the Saints trade up?

I expect to see us picking up some unkown LT from some hide away small college in the 4th or 5th round. There is little doubt that that is what our draft scouts have been tasked once again to dig up and find! They are looking for that OL steal that we have been very fortunate to find in the past. Probably our strongest draft asset. I don't think moving up will happen for an offensive lineman, more likely if we did it would be for a defensive player that Ryan and Payton really like. I prefer we stick with what we got and get the best players available in each round. But who knows, stranger things have happened and this year it kinda feels like almost every position has a special need for a starter or more depth.
