Like Eli mentioned, the G12 call is a yellow card to the alliance. Beyond that, the interpretation on the refs part was interesting and in the discussions, I’ve been involved in, C01 could’ve been cited alongside that, a rule that really is up to the discretion of both the referees and head referee to dole out the respective color of the card(s) itself.
In no shape or form represents that of my team + whether you like it or not, some rules are discretionary on how strict/ lax refs are about calling particular rules but anyways, back to answering OP’s question…
Personal hot take and opinion: based on my interpretation the blockade in question, 649 and/or 1678 could be cited on C01 individually should the referee posted in the top and bottom left corners feel their actions to be egregious. In addition, 1678 coming in, whether purposeful or not, though it looks to me just like they just wanted to keep up their efficient cycle times, still in the second instance, with the end game beginning and really no reason to keep the scale going with a defining win already, could’ve been cited on the rule; I understand why 649 didn’t let down their insane defense but ultimately some combination of those instances and rules caused the refs to unfortunately take away their win. 254, unfortunately, was a bit of collateral damage but as the clip shows, 3310 was stuck in their portal/ the red exchange zone for up to 20s ::rtm::
Final take is that the call shouldn’t have had to be reversed in such a dramatic fashion, with more time on the referees parts that should’ve been spent on a final ruling vs. the reversal that broke 4 team’s hearts. It doesn’t seem to be fun to be either a winner/ finalist right now, however, this hopefully is a learning lesson for all future off-seasons but the head refs call is the head refs call.
Just for reference and so hopefully everyone below can create an informed opinion (and credits go to everyone who clipped the calls):
