A VERY dangerous job. A friend of mine was killed a few months ago in a starting gate accident, and he was an amazing handler.
Some crews ARE just bad, and plenty of blame for that can be put on the starter as he’s the one in charge and it seems from my experience that when you have a forceful and impatient starter, you’re going to have a similar crew. The starter is often in charge of schooling in the mornings so if you have bad schooling then, it’s going to show. We had a particularly awful crew in NM who worked under a horrible starter (who, if a horse would even look funny when walking to the gates schooling he would bring out a whip and crack them). However if you went to a track in the same circuit under a different starter with half the same crew, they would be totally different, much calmer and patient with the horses.
I think they are necessary to have in the gates but I do agree that many horses would be better off without being held so firmly. However their job is to protect the riders and they need to be prepared for a split second explosion. Getting them into the gates every second counts and there isn’t any time to play games, it could literally cost somebody or some horse their life. And I’m sure you are seeing “new guys” on the crew, that might not have a ton of horse experience (with it being such a dangerous and low paying job I can’t imagine tons of people are lining up for it-they probably have to take who they can get). There is a lot more to horses than just leading them forward and they have to learn along the way how to read body language and handle a horse in a wide variety of situations.
