The quality of the 2016/17 Mitchell and Ness jerseys was higher (the year before the one you posted). Hard to appreciate the difference if you haven't compared the two. The 2017/18 jerseys were way too baggy and loose - even on the players. It wasn't until late in the season that they fixed it but by then it was too late for retail jerseys. The current season jerseys fit a bit better - especially if you've got a more recent batch because they're actually made in Australia as opposed to China.
For some reason the heritage jerseys were a completely different style and fit. They were the best NBL jerseys Mitchell and Ness put their name to.
I agree with what you’re saying but I also preferred the 2017/18 jerseys- as a bigger guy I liked the loose/light fit. My 2016/17 jersey felt too heavy, wasn’t as long and not as breathable on hot summer days
