Funny you mention that. I am going to use that as a rule for my new franchise that I'm starting tonight. But it will only apply to the 2016 season (year 1). Going into season 2017 (year 2), everyone is fair game. This way a guy like Karlos Williams will get scooped by a team in need. I'm going to scoop Flazko's boy Darius Jackson after final roster cuts are complete. Since I already know that in advance, using the house rule for initial free agents makes it fair.
