I really don't get this 2 Hookers mentality, it's just wrong on so many levels and I've never seen it once benefit a team in any way. Dragon's coaches of the past persisted with that dubious strategy for years and it never helped once that I can recall. And now with less interchanges it makes even less sense.
If your hooker can't play 80 minutes and do his job then get a new one who can. You don't change your 1, 6 or 7 halfway through a game unless you're forced to. Hooker is only a forward in name. Your props, locks and 2nd row are the big dummies, run, tackle, don't think too much, they're interchangeable. The Hooker is different, he is part of your spine, directing and organizing in the most hands on job on the field. Everyone relies on him so much for all the basics and expects him to be in the right place at the right time and unless you have 2 Hookers who play exactly the same game you're going to mess with everyone elses expectations and change the whole structure and dynamics of your game if you swap them out.
Plus it takes a very skillful coach in my opinion to even mess with the prospect.
No two Hookers play the same game, most are completely different, speed, passing, running, kicking, positioning, all different. How can you expect the rest of the team, mid game, to suddenly adjust and Why anyway ? Because your 1st choice needs a rest ? You're losing and you have no faith in your 1st choice hooker but think your 2nd best hooker can suddenly save you ? If your 2nd choice Hooker is such a game breaker why the f**k is he on the bench ?
Makes no sense to me, it's a desperate and disruptive move with no real benefit. Like a bad move from a poor coach.
