We can talk about where we'd like our current players positionally, the truth is that a lot of this will be dependent on the free agents and/or players we can get via trade.
You go get the best player(s) and then plug in our current guys where it makes sense. Without knowing who we can get, we're just going in circles.
It is good to have some flexibility positonally but I'm sure the front office can't be stupid enough to go to the other extreme again by totally neglecting defense.
