I wouldn't worry too much about his speed. He barely played any footy prior to his first grade debut. The fact he's getting through so much work with ball in hand to this point is amazing. He is then pushing through the middle, linking out wide and covering plenty of ground with out paperthin defense
Looks to me like a pretty special kid with a tough mindset. In a years time If he's still dragging his feet after having no ball for 35min and then making a break from your own line then we can ask a few more questions.
We need to allow this kid to grow into the role and appreciate what he is actually achieving l, given his preparation.
Not trying to rip into you either if it came across that way
