“Roethlisberger then began walking forward and appeared to say something to Seymour”.
Well, what did Roethlisberger say? What was said probably played a big part here.
Doesn't matter. If you're not disciplined enough to refrain from punching someone who's talking trash, you deserve to be ejected. Everyone in the NFL knows that an actual punch (open or closed fist) will get you tossed.
I thought the same thing. Seymour’s reaction was so swift to whatever Rothlesberger said that I wondered what the hell he said.
And I agree - the officiating was absolutely awful.
