Kick is quite a good fit on the Wrackle lino who you generally want off the LoS but it takes a while to get that combo and you'll normally have a guard or even a +stat lino taking that final spot on the field by then.
The biggest problem I've found with moving to a 4 Catcher Human team is that I have no space for a kicker on my team anymore. I'm contemplating giving it to one of my unlevelled Catchers (and delaying by one level creating a new Wrestle, Dauntless safety).
