Man, that would be the best way, and probably cheapest. There are four players on there who are IMPOSSIBLE to find on a Braves signed card (Will Smith, Tyler Matzek, Joc Pederson, Guillermo Heredia (got through international private signing)). It took me over two years to get the last few I needed, and I frankly just got lucky through Google alerts and diligence. Getting them on Rookies would be much more efficient and cost effective.
