Why do you think Watford, Laurent, Williams, and Banks will be gone? Of them all, I can really only see Teddy possibly retiring, and Banks has already said that he is willing to take a smaller (see what I did there) role on the team. Watford is an experienced QB who already knows the system, and I see no reason why Frankie would want to leave unless his post-concussion syndrome doesn't improve.
With Kalinic trying out for multiple teams, he may make it onto some type of NFL roster, and then we're down a CDN receiver/FB, so Ungerer III may be a priority, unless we want to go with Burt as our only CDN WR/FB.
You should have also put Jordan Murray on your list, as it looks like we need a new Left Tackle, because the team released him to persue an NFL shot.
