I agree, I wasn't meaning to suggest the same exact technique was used,
rather that one analogous to or inspired by that technique was used
(well, not inspired, exactly, but you know what I mean).  INstead of
immobilizing their prey, several attackers would leap toward the animal
hoping for a good position; the lucky ones who round it would anchor
themselves with their foreclaws and one sickle claw and make a good
slash in the appropriate area with the other.  You're probably right
about the amount of precision required being too great, and while it
might be anatomically possible I can see how it would be an unrealistic
attack; this is especially true when you consider that the attack would
have to be enormously effective to have so much success evolutionarily.

Ah well, it was just a thought.
