My impression is that lions are much bigger. At least a lion can kill a
hyena (as was shown in the show).

If all large theropods are scavengers, I agree, we have a big problem.

I disagree. Pack tactics are to CHASE a subject down, wear it out, and
then kill. When a subject stands and fights, the individual members
get shy, unwilling to risk injury. In the case of another larger
predator, it is generally better to be patient and wait for it to
eat its fill.
