Because of how referee assault suspensions carry over into other competitions I think they'd have to.
The next choice was Karl Ouimette, who is qualitatively not really a drop off from Zubar. A bit less physical, a bit better on the ball. Marsch likes Zubar for his complementary play to Miazga- Zubar is closer to Perrinelle, Ouimette is a positional guy. In either case, DC's tactic of knocking hopeful passes to Saborio and hoping Rolfe and Espindola could catch up to the play wasn't going to threaten any of them.
"Pundits"? The only "pundits" who I have heard say it was an indisputable red are Alejandro Moreno and Simon Borg. I've heard more "it could have gone either way" and even more silence - apparently it was so ordinary that most "pundits" don't feel the need to comment on it. In any case, Peter Walton felt that it was clearly a reckless yellow. This was not akin to a Mullan v Zakuani clearly violent challenge.
I actually agree with you. But as a mental exercise, if Zubar had actually broken Halsti's leg, how many games do you think he would've gotten?
Oh for god's sakes. Every DC fan I've seen has said that the better team won both the match and the series. In fact, one said so in the very post to which you replied. If you think folks are wrong with their assessment of the severity of Zubar's foul, that's a reasonable position to take, whether right or wrong; but your post is strawman-beating at its finest.
