Actually the rule has always been if you miss two picks, the commissioner makes one to keep you close to the pack.
It may not be posted in this thread, but I specifically remember him saying in past seasons that he would make a pick that best addressed a hole in your roster, which he did.
Clearly he forgot your Beckham pick, I'm not disputing that. He saw your hole at 3B and picked you the best available third baseman, I'm guessing.
