I actually agree with the idea if we can truly address the balance issue, the smaller the change needed the better. The question I suppose is what kind of change will work, hence how big does the change need to be.
An idea I've sort of kicked around but I'm not sure if it would be sufficient is to change shotblocking into the skill that determines how effectively any shot is contested, and use OD/ID more for the non-shooting aspects of defense. I don't think it would do enough to address the imbalance in OD vs. outside offense, but it would at least require some additional investment in SB to avoid being victimized by jumpers and threes.
I think your original post would be a great transition to a non-MMO type of game in the vein of Football Manager, which has approximately 3.5 buttloads of player attributes and for the most part they all actually matter. If there was any indication that there was the staff and inclination to do a BB 2.0, having a few additional skills and maybe increasing training speed while making sure ultra-imbalanced builds are punished could work too.
