It does make sense for them. They need a 20-carry pound it between the tackles sort of a running back. And we all know that LaDainian is more than that right now. But here's the thing.
They don't match well. Why? Because the Saints have three picks this year. They do not have the key round picks for a talented player with developing questions. It's a 1, a 4 and a 7. Now sure, they could offer a player like Pierre Thomas in the off-time, but you know what?
You need a good package of picks coming back. New Orleans just does not have the necessary oomph to get LT. They don't need receivers. They don't need Jeremy Shockey.
