Four years ago, the Chicago Bulls' Derrick Rose looked destined to be the point guard on which all others would be gauged.
Fast forward to 2016, however, and a combination of circumstance and skill have seen a certain point guard plying his trade in the Bay Area take that mantle and run away with it.
But, as Rose and Steph Curry prepare to go head-to-head for the first time this season, tonight's Bulls vs Warriors game should be seen as an opportunity for D-Rose to make a statement rather than a look at how he has been left behind.

Rose sat out the Bulls' 106-94 loss to the Warriors back in November, and, as such, this is the first time the 27-year-old will share a court with Curry since January 2015.
Since then, Curry has gone on to win an MVP award as well as his fist championship ring on route to becoming perhaps the NBA's biggest star.
What's more, tonight's game comes just two days after Curry led the Warriors in dismantling Messrs James and Irving on their own court. If Rose could make a stand at the United Center it would send a message to the entire league, that's for sure.
As Jimmy Butler put it: "I'm sure everybody wants to see that matchup between (Curry) and Derrick...I want to see it along with the world."
The game will actually be the first in NBA history in which two MVP-winning point guards will meet and Rose will want to remind everyone that he is deserving of that prefix.
Battling back from injuries that have ravaged consecutive seasons, Rose hasn't exactly been vintage this season. He's averaging a career-low 15 points-per-game and has seen Jimmy Butler take on the lead role in the Windy City.
He has improved since the turn of the year, however, averaging closer to 18.5 ppg since Christmas.
One lockdown game against Curry isn't going to see him usurp his Golden State rival, but it is essential if the Bulls star wants to convince the rest of the league that he deserves to be in the conversation when it comes to the elite PGs of the game.
The Bulls want the win as it will serve as a watermark on their season in light of the Cavaliers' recent struggles against the Warriors.
For Rose, whilst a win will be his main focus, outscoring and outmanoeuvring Steph Curry - as he did back in January 2015 - is just as important.
