The bolded is just outright crap. He’s covering far more ground than he ever has. And is stronger than he ever was at Footscray.
But you are right in saying he isn’t as fit as he could be. But everyone should realise he is transforming from an opportunistic half forward into a midfielder who spends time up forward. This won’t happen overnight. It takes time. He has made enormous progress with his fitness since he arrived at the club, and will continue to do so over the next couple of years. This is not fantasy land where everything happens instantly. This is real life where things take time. Jake is coming along beautifully, and if he keeps progressing at the rate he is, there is no reason he can’t be one of the best players in the comp in 2 - 3 years time. You need to get a bit of perspective.
