Whats the difference between the way Sonny Liston, and Larry Holmes threw their Jab?

[OMGWTF]

Not in terms of how it was used (tactically) or their physical qualities (like speed etc), but the technique itself.

Hint if you think they jabbed with the same technique (or see this question and dont answer) you have poor knowledge of technique.

Whats the difference? (im testing you guys)

Their highlights are below.
