The best thing they could do (which is why they probably won't do it) is to bring in a top quality executive (GM, President, Czar, whatever) and give him complete autonomy. This man needs to be experienced, well-connected, and respected around the league. That's the only thing that will change the perception and make San Francisco a desireable destination.
Any HC considering the 49ers can see that the roster is weak and the team is at the beginning of a multi-year rebuild. The only thing that makes that situation attractive is the opportunity to put your own stamp on the team and build it the right way. If the right structure is in place, it's an attractive job. If the existing structure is in place, failure is assured.
The Seahawks had no trouble attracting Pete Carroll because they gave him the one thing he knew, from experience, is essential to success in the NFL: the right Front Office structure and a GM that he respected and knew he could work with.
For the Yorks to succeed, they have to do the one thing they can't bear to do: hire an outsider and give him complete control.
