Here's an approach. Maybe not the best approach, but it could be like plan 5c or something.
If Alex Len falls to the ten, then you invest in the future. You grab the aforementioned at the ten and acquire another pick between 12-20 somewhere and grab Steven Adams or whomever the paul allen team deem BAC, there will be a bunch in that area.
2013-2014 will be pretty painful to watch. It's true. But hurrah for the draft and the crazy FA field. Now you got 3 possibly promising young centers. One of them is clearly the best for our system. You keep him. Number 2 is trade bait for picks in that wonderful lottery coming up next year and number 3 is your backup.
Center Problem solved. Center of the future acquired.
