Brown had the peripherals of a guy who could legitimately start game 1 of a playoff series. He also had the best peripherals of any SP on our team.
Now obviously peripherals ignore batted ball data, and that's a huge part of the story with Brown. But as we all know this stuff is really fickle. In 2025 we can't just point at BABIP and say "luck!" but it is mostly luck. Some light math says the YoY correlation on barrel rate is .45 and on hard hit rate is .55. That's not inconsequential but it's also a far far cry from a permanent death sentence. For instance, among pitchers who pitched 100+ innings in '24 and '25, Carlos Rodon had the worst barrel rate in the league in 2024. In 2025 he was 93rd. You need several hundred innings before you can say a pitcher's batted ball outcomes, good or bad, are meaningfully predictive.
I also don't buy the two pitch thing as some sort of crippling problem either. Setting aside that there's plenty of pitchers that do great with two pitches, it doesn't track with how Brown has primarily struggled. A limited repertoire is usually associated with heightened struggles deeper in games. Essentially the times through the order penalty becomes magnified because the pitcher lacks a variety of ways to get outs. That's why these guys get funneled into relief. However Brown's biggest struggles were early in games. Brown had an ERA of 9.00 (!!!) in the first inning, his highest of any inning. He also had his worst peripherals (an xFIP of 4.38). That should have absolutely nothing to do with only having two pitches.
Brown's 3rd time through the order ERA is also pretty inflated (13.19...even in a small sample woof!), but I think it should be noted his peripherals were still strong. But while I'm clearly quite bullish on him with a little more sample I would buy Brown's going to be limited to being a 5 and dive guy due to his lack of repertoire.
Now I don't say all this to imply we should go into next year with Brown in the rotation. His struggles seem pretty flukey, but you can't just assume it'll all work out immediately with the clean slate of a new season. But I do think it's reasonably likely that in the near future he's a SP that we actively want starting games. So I do think he should be near the front of the line among the depth SPs, whether that's in the bullpen as the long guy (my preference) or at Iowa as the first SP on the speed dial.
