It is a dice roll joke, it started among a few of us in beta.
The point is, Big 6 teams don't need to worry about all other teams now. They need to worry about how they've prioritized their recruits. When you accept that other teams aren't - or at least don't need to be - scared off by your mere presence in a battle, you focus on the fact that your A prestige means a lot, and if this is the guy you want, D boners can't fight you for him. But if he's not a guy you're interested in rolling for, then you assess whether or not you can reasonably expect to get him without a fight. Maybe you can, maybe you can't, but you should have a number of these guys you're watching, if you're playing by the "go all in on max number" strategy. That's why I say if you play that way, you have to be ready to move on if another team looks like they've prioritized him, and are willing to go all in. That's is the natural and reasonable consequence in a commodity game. If someone values the commodity more than you do, they'll be willing to spend more, and so can get the commodity even if they don't have your resources or advantages.
