As someone who manages people for a living, the problems on Team 2 were entirely your manager’s fault.
I did not escape without a bad review. Somebody had to take the blame when things didn't work out. That was also some textbook bad management: my poor performance was first described in the meeting where the review was delivered. Never once in all the 1-on-1s we'd had. Skip said there was nothing that could be done because all that mattered was that I did not deliver compared to my peers.
My manager moved teams then left the company not too long after as well. I'll never really know what happened, but I assume they got a poor review themselves.
Hopefully after a few of these ice breakers, everyone will have a better grasp of each other and more natural communication and relationships might come about.
