Peak Jimmy is playoffs Jimmy, which is a #1 option on a finals team. Most loved Castle's upside and he's exceeded every expectation, but he's not close to that level yet. Let's keep the sanity.
*Jimmy Butler was the veteran face of a
#7 seed, ensemble team built around defense, who was 1a to a 25y/o AS Bam's 1b*
But fine. RIP Hamilton was the #1 option on a finals team. Not all #1 options are created the same, but Jimmy was the guy, Jimmy hugely stepped in up in the playoffs and took his team to the conference finals, then the finals.
I'll retract peak, because I think you lost the point in semantics. The regular season is the only thing Steph has played, I was purely talking about historic, regular season performance.
Steph is already playing at 25-28y/o Jimmy Butler level this season and in a similar role. He's the #2/3 option behind HOF Center and a multi-AS PG who gets the tough D match-ups. (Will you get distracted by HOF Center? Wemby is not a HOF center, he hasn't played long enough, let's keep the sanity)
Comps are never perfect, but this is a pretty good comp and I don't think people realize how close it is today. That was the point of the post. Not reading into peak.
Jimmy was 25 and the 3rd option behind Rose and Pau when he made his first AS team. Soph Steph had objectively a more productive season in 8 minutes less per game.
Similar story the next yr with a beleaguered Rose giving Jimmy a marginal jump in usage. The next yr Jimmy was 1b next to hometown hero Dwayne Wade with another marginal jump in usage.
It is not insane to note that Steph, this season, outpaced what Jimmy Butler did from ages 25-28 in: ORB% and DRB% and Ast%. Their TS% and FTr and usage are all extremely close. Jimmy had a slight edge in Stock% but as a scorer Steph has an identical per 100 scoring rate before Jimmy's usage climbed.
That is objectively the level Steph has maintain this season. Jimmy played more minutes, Steph has gone from <26mpg to start last yr, to <29 to finish, to >30mpg and climbing. Steph is playing at early-middle prime Butler level today.
