I don't agree with the assessment that a C uses all arm. They, too, use most of the body.
MLB catchers average 82 mph on steal attempts.
Why so slow?
Look at the first three video clips of the link you provided. Clearly, with each, there is significant weight shift, leg drive and core rotation providing much of what is behind the throws. Of course there is some sacrifice of velo when emphasis is put on quick transfer and release. Pitching, particularly from the set, is the opposite in terms of having time to maximize every movement of the body in order to fully maximize velo, plus it is downhill. But the basic fundamentals and involvement of lower half and core are still very much in play for proper catcher throw downs. Shorter circle/take back, slightly lesser stride, quicker release and level ground all factor into the difference between an MLB P throwing 90+ and a C throwing low/mid 80's.
