Gosh, I was that guy.
I am still not entirely sure how I feel about it. I know teammates respected my compete level and knew I always had their backs. But I also felt like they hated me a little (or a lot).
I can say with some certainty they did things with more zest to avoid me targeting them during a game with a comment or tirade. But I still wish I didn't need to go there in the first place. To be fair, if I was mailing a game in, I wanted to be informed about it in the same direct fashion. I certainly did not want to be the one dragging the entire rest of the team down.
It didn't always feel great. But I reckon it can't be all bad. I captained many of the teams I played on, often by player vote.
