I didn't like it. Yelling is fine, but he seemed to go overboard with it. When you see a player (Kamara) trying to hold a coach back during a tirade, then it's more than "just football" at that point.
I really can’t recall an NFL head coach in the last few decades having a similar meltdown on the sideline. Harbaugh with the 49ers may have been the closest, but his meltdowns were directed at the officiating best I can remember.
