Stanley Johnson is a born competitor. From all accounts of training camp and this summer, he's a born leader. He even said that he was the best player in his draft. So it would be no surprise if he takes ESPN's Player Rankings as more fuel to his fire.
Coming in at number 206, Johnson ranks ninth in rookies on the list. Some are no surprise to be higher than him. Karl Anthony-Towns, D'Angelo Russell and Jahlil Okafor have yet to be ranked. Kristaps Porzingas, Willie Cauley-Stein, Emmanuel Mudiay and Frank Kaminsky III are all also ranked ahead of Johnson. So is Justise Winslow.
These rankings are done almost exactly the same as other ESPN rankings. A list of voters give their votes, they're aggregated and presented to the public. Mind you, ESPN says that the voters were not only supposed to take in the QUALITY of the player's contributions, but also the QUANTITY. So, if a player is going to have a bigger role on a team due to need, they will likely be higher.
Winslow is listed on ESPN as a small forward. As such, he likely sits behind Luol Deng in the depth chart. If you look at the team-by-team listings, you'll see that they have Winslow right behind Deng on the team's roster, but Deng has yet to be ranked. Johnson is also behind his presumed starter, Marcus Morris, but he's also behind Jodie Meeks (as far as team listings go). Either way, they are both backups.
Johnson, however, is catching Stan Van Gundy's eye in practice (though there's only been one so far). There is a slight possibility that he could end up the starter by the end of the season. Winslow will likely have an opportunity to start due to Deng's injury history, but will doubtfully be the starter when Deng is healthy.
Eh, what can I say. #DetroitVsEverybody!
