It's an insurance move, although I suspect he may take Hudson under his wing anyway. Wouldn't surprise me if Hudson ends up being his project. And, if Rondo DOES get hurt, they could bite the bullet, waive someone and have someone ready to go that's about as good as any street free agent that would likely be available.
Still waiting, though, to hear the team announce that they've signed Michael Sweetney as "Team Nutritionist."
