It doesn't look like we ever voted on it though.
It's easy to track in the roster app because players like McFadden still have their draft position listed in the Flags column (e.g. McFadden shows Trade/Reneg 5/11/10 2008 1.01). I can make it even easier by changing the font color of those players still in the first 5 years of their rookie contract.
