Let's try something...
Power without intelligence and talent is less effective than power with intelligence and talent. Do we agree on that?
A 10, on the surface and as general logic goes, would need to be of higher intelligence than a player in most other positions.
But is that the case?
One could argue that the things a 10 does are very visible but the complexity level of his role isn't necessarily higher than, for example, an 8.
A ten would have to call plays, decide whether to pass, who to pass to and if kicking then what type of kick has to be made. And then the 10 would have to make defensive decisions.
How many decisions does an 8 have to make and how complex is his role? An 8 plays most of their rugby without the ball in hand. Even the most linking of 8s still does most of their work off the ball. Either defending the ball or pressuring the opposition ball. This is, by default, doing to be less "visible" than the things a 10 does.
So the question, how much intelligence is required?
Some decisions an 8 has to make(GPT);
- Keep it in, pick, or release to 9 at the base
- Pick short side or play open side
- Pick and carry, pick and pass to 9, or pick and link to 10/12
- Detach early as a carry option or stay bound to secure/steady the ball
- Clean pickup vs leave it for 9 when the ball is messy
- Call/adjust 8-9 link timing (hold, go now, go after set)
- Carry tight at guard, carry at bodyguard, or tip-on/out the back into space
- Carry to win collision vs carry to stay on feet and place for speed
- Take contact and go to ground vs fight for extra metres and risk isolation
- Offload in contact vs secure ball and set ruck
- Run a decoy line vs demand ball as primary option
- Hit ruck vs stay out to reload as next carrier
- Clear past the ball vs stop short and “post” to protect the 9
- Compete/jackal vs stay on feet and fold to the next phase
- Contest breakdown vs leave it and fix the defensive line
- Stay in the tramlines to hold width vs tighten in to protect around the ruck
- Fold around the corner vs hold the line and keep spacing
- Track, drift, or shoot on 9
- Track inside runner vs press out to shut down the wider option
- Take the first receiver (10) vs slide to 12/13 vs stay connected to forwards
- Commit to a tackle/assist vs stay up for the next threat
- Target ball-carrier vs target the support line to kill the ruck
- Rip attempt vs complete tackle and reset
- Slow ball legally vs release and get back on feet immediately
- Call for a counter-ruck vs set the next defensive line
- Choose who to “hunt” (9/10/inside shoulder carrier) based on cues
- Hold backfield/edge cover vs join the front line (phase/field-position dependent)
- On lineout: be lifter, be tail/transfer option, or be first cleaner/guard defender after the catch
- On kick receipt: carry back, set a ruck, pass to 9, or link to a pod/backline
I read though these and while I don't agree with them all, it does demonstrate how "dumb" muscle wouldn't cut it in the best pack in the world.
There are simply too many decisions to make for a guy that is "just strong". Wiese is by some distance the best 8 in a country packed with ridiculously talented loosies. There are 100% other 8s that are as stronger and faster than he is. So if he is dumber than most of them...why is he so effective?
I'm reminded of a story I heard somewhere, can't remember where;
A famous Samurai visits a feudal village in Japan. Everybody bows. One man does not. The samurai dismounts and asks the man why he didn't bow? The man replies that he didn't bow because he possesses a skill greater than the Sumarai's. The Samurai insists that he demonstrates this skill...
The man gets out a jug full of oil and with his other hand he makes a small loop, about the diameter of a pinkie finger, by curling his forefinger on the inner side of his thumb...
He then proceeds to pour the entire jug of oil into another jug, though this tiny orifice, without any of the oil touching his forefinger or thumb.
The Samurai gets on his horse and leaves.
The next year, when the Samurai again visits the village, he gets off his horse and bows to the man.
