I would call everybody's bluff and pick Rubio.
He clearly is coveted by many teams and if they aren't willing to deal before the draft they will after...
the agent will be upset, but Rubio wants to come over here so they will figure out a place for him to land.
plus, getting drafted second will give him the funds to pay for his buyout.
IMO, sooner rather than later, a team like SAC will make a good enough offer to make it worth it to have gambled taking a player that doesn't want to play for you.
