I'm really happy that we have a manager that's willing to look at all these type of aspects, but here comes the but.
Things like sports scientists, IMO, are for times when your team is 90-95% to perfection of performance, you bring in scientists/nutritionists/whatever to maximise the performance within that last 5-10%, wring every last ounce out.
Where we are just now, we are nowhere near that 90%, and what is needed to get us there is hard work on basic fitness levels, tactics and organisation, which is what Murray and Jack are there for.
The analogy I can think of is either a swimmer or cyclist who shaves their body hair, so that it makes them 0.1 second faster over the course, that 0.1 second might be the difference between success and failure. However, if our team was a cyclist or a swimmer, they currently have a puncture or are too fat to get into their swimming costume. There are bigger priorities and gains to be made than spending funds on a consultant sports scientist.
Again, as I said, just my opinion.
