To be fair, he's not actually being paid to be a superstar just yet. That starts next season 😄
Maybe that's being silly, but it really is the primary point here. He's 23 years old just finishing his rookie contract.
To act like he should match or outplay Brunson in his first playoff series is ridiculous on many levels. First, Brunson is 28 years old on team that has the gravity of KAT, OG, and Bridges to help him remain in 1-on-1 coverage. The Pistons weren't blitzing him with doubles and traps all series like the Knicks were able to do to Cade. It was just Ausar or Shroeder on an island.
Even with that, Cade averaged 25 pts, 8 rebounds, 9 assists, and 3 stocks on 43% shooting compared to Brunson's 32 pts, 4 rebounds, 8 assists, and .5 stocks on 44% shooting. Sure, Brunson is a better scorer in the clutch right now and his points are there to show it, but they aren't light years apart and Cade has him on all of the other numbers while playing both ends of the court unlike Brunson.
And I'll repeat, he did that in his first NBA playoff appearance while still on his rookie contract with no real help. It's no surprise he ran out of gas in the 4th on most nights. Meanwhile Brunson is 28 years old having been to the playoffs for the past 5 seasons, while on a team stacked full of high gravity players built to contend for a championship.
What Cade did in these playoffs was actually quite remarkable and should be commended.
