Jump at Stanley and Robinson right away, and pay enough that one of them says yes. That should be the team's first play. That gives you
Stanley/Cam Robinson
LG (Tyrese Robinson)
Andrews (Strange)
Onwenu
RT (Wallace)
At that point, you don't need to go nuts and spend through the roof for the highest end guards, because you don't want to be giving big money to Martin or Scherff given their ages and/or injury histories, so you focus on 1 or 2 from the next tier down.
Once you've done that, you're looking at depth and a RT competition between Wallace and either that first round pick (Campbell/Banks) or a FA tackle, if you go in another direction in round one. And you've got a line that's held hostage to, at most, one position, instead of 4 like last season.
