Wolf is going nowhere at least until after the first few weeks of free agency. Of course, Kraft might hire a GM in January who would make all final decisions and provide direction and leadership in the free agent process.
Folks ignore the enormous amount of work to do, starting with detailed folders on all potential free agents (and on a few trade targets). As we come close to free agency, a list of targets and priorities (e.g. who are the best LT's and how many do we want?). In the scrum the week before and the week after the season starts, there needs to be negotiations with lots and lots of players.
A GM could bring in his own staff, but he will need to use a lot of what is already done and what will be done until he is hired and has hired at least some of his people.
