would you sign this youth if you were me?

Depends really, he will tire less than most, I've been using 2 greens on average between each PT session with my academy 18 year old), but I get a lot of the greens through watching Vids on my devices (2x iPhones & an iPad), so I would expect to use far less Tokens than that

How do you figure he will tire less than most? that would depend on his fitness skill and it should be the same as any other player of his quality, give or take a few points.
