We have some legitmate holes on offense. We're spoiled in thinking that our offense is just going to continue to be a juggernaut over time without using some significant assets on that side of the ball.
Can't green thumb this post enough. As much as I'd like to see our Defense improve this team will always be run by the Offense while Coach Payton is HC. Think about it, we almost made the playoffs last year after a 0-4 start, with no HC and a historically bad Defense and honestly, if it hadn't been for our Offense not being as efficient in previous years - we probably would have!
My point is this; our Offense must stay at the top to keep this team in the hunt. The Defense only needs to be decent. Last season our Offense slipped because we had turnstiles at manning the Tackle positions. FO.com actually wondered in the end of season rankings "If Bushrod hated his QB" he played so badly.
So with that said, I'd be over the moon if the Saints could use one of the flashy names (Tavon Austin or Geno Smith maybe) to trade down from #15 to the mid to late 20s and secure more picks and strengthen the Offensive and Defensive lines.
