Historically we have tended to use the 4th tackle as a set up play. Someone like Gal takes a hit because he is trying to get to a certain spot and hopefully get a quick PTB. Chad knows how we want to kick it from that spot but SJ would also be free as a kicking option or to launch a running raid.
Pros and cons to this method because you are throwing away being a threat on tackle 4 to make your tackle 5 options better.
If we choose to run a play off the half where they challenge the line on play 4, to make that more of a threat, we risk affecting quality of tackle 5 options. Which is exactly what we saw happen, especially because it was our better kicker.
Maybe the answer is try and have Moylan do it but more so I would say the answer is we just need to get better at it.
A lot of our team are used to tackle 4 being a set up (almost rest) play. Whether it's Hynes or Moylan they should have better options available and be less likely to be caught with ball as a result.
To some extent maybe also still keeping tackle 5 set up in mind ie Hynes would rather go down in right area of field for our preferred tackle 5 than take an option that is only okay, but plays away from there.
So there are probably a few elements in play here but the end result may be we play a style that is more threatening on play 4 on average, but means more sloppy on play 5 on average, vs recent years.
