It's got more to do with playing in a stadium that's three times too big imo. Theres never going to be much of an atmosphere until you get a crowd up past 10k. If you get past 20k, the atmosphere is electric At 5k, it's not great.

If I won £150m on the lottery we'd be out of that ground and into a purpose built 13k stadium in a flash. Preferably at Fartown!

But Cracker Jack said you can’t make people faster so no point, however unless he is a sprint coach he can’t really comment

Taken out of context but no problem.
I'm saying that it's probably a small percentage increase to someone who's got natural speed ability
Otherwise with all the expert " sprint coaches" there are in the world the Olympic record would be broken regularly.
A good sprint coach yes could probably get a few more yards out of say both Walmsley and McArthy Scarsbrook but I would still claim the latter is naturally the faster of the two and that's what the good lord gave him - not a coach in a track suit.
You have your opinion and fine
Farah and Christie are both human beings.
Both top athletes but the finest respective coaches in the world would never make Mo a 100metre sprinter despite his finishing pace or Linford into a 10000metre runner.
It's down to timproving the basic natural ability they are blessed with and in some cases that could be negligible or near its limit when they become involved
It's nature..
Lotta good racehorse trainers out there but the really special horses are the ones with natural ability in their particular aspect of the sport. Jumpers aren't sprinters aren't stayers

Just my opinion

I think the point is that "a good sprint coach yes could probably get a few more yards out of say both Walmsley and McArthy Scarsbrook.." and across a squad that might be the difference between finishing fifth or first.

Which is a hell of a lot more interesting to me than an entirely academic argument about whether its "god given" or coached.

IMO the attitude here is the reason why British RL is so far behind the NRL. All British players should be having sprint coaching to gain that small percentage increase.

That's not quite what he said, to be fair.

Steady fella!
Natural / by nature
I'm told that doesn't come into the equation!
With the right coaching he could become what Jerry needs - and they might just also get him running faster than he can after bulking up.
Genetic qualities count for little ...
