I’ve been asked to clarify the following rule, so here it is – it can also be seen in the rulebook page (see top menu bar):
6. No access granted to “full” teams, notably those with 12 forwards, 6 defense, 2 goalies, to the auction draft. What this means is that a team with a full squad of 12-6-2 CANNOT BRING UP A PLAYER FOR AUCTION AT THE AUCTION DRAFT, as has been the case since the very beginning. If a player is brought up by another GM (assuming that team can in fact bring up such a player, where he has less than 12 forwards, 6 defense or 2 goalies, and brings up a player of the position that he is lacking in only), a “full” team can bid on that player, on condition that he has sufficient draft picks to cover the additional player and to be able to drop the latest pick as a result.
