I see it differently. The alphas controlled the course of events, even the lions to an extent. I doubt that calf survived after that mauling. But, if it works for you...
You see it differently? Ok, you're right to see things as you please, and conjecture about the outcomes to support your agenda.
And since we're on conjecture...my supposition would be that the lioness that got the horn and was thrown through the air was the most likely to have died as a result of the day's events.
In any event, the heard isn't always wrong. In fact, the majority, centerist view, is usually farily well rationlized and conceived. However, there are no absolutes. And in the case in the video, the herd ruled the day, though they may have had the weakest individual of all the combatants. The complete independant (the croc) got just barely a taste, and the lions paid a pretty high price and netted nothing for their trouble.
