A sneak peek at the ZiPS x @fangraphs.com Depth Chart for the first team to go in the ZiPS projections in 2026, the Philadelphia Phillies.
Obviously, this is not the 2026 *team* projection and the roster will have quite a few changes since it's, well, November.

I'm sure the Brosnan tsunami surfing scene was 100% realistic and the CGI will age amazingly.

I don't know why people get my first name wrong more often than my last name. Not mad, it's just really odd that after "Szymborski" the most popular boys name the year I was born woudl be the hiccup!

It's always amusing when people think pitchers from the 1950s had invincible arms, when the attrition rate was terrible. And it was known at the time, and there were even predictions in the future that have almost come to pass by 2025.

Post you from a different era (1990s).

I'd really like to see what Polymarket is theoretically considering a finding that Jesus Christ returned. Does he have to have a press conference about it?

Had to put my oldest cat, my slow-witted-but-friendly tux cat, to sleep this afternoon. You always think that it'll get easier, but it never really does. He had had early stage kidney disease that was being managed, but at 17, kidneys can suddenly go down really quickly.

But if you instead keep R steady instead of HR rate for the home run era data, you get less movement.
(Again, I know there are more robust ways of doing this, but it's illustrative, which means I don't have to play math teacher, which I'd be awful at)

Remember, it's stdev/mean, so we're already scale-invariant.
There are more robust ways to do it, when you model coefficient of variation based on just R/G and HR/H%, the HR/H% is a massive variable.

2025 teams of HR as a percentage of hits vs. game by game coefficient of variation for runs (st dev over mean). This is consistent with historical data, in which about 20% of the volatility of a team's game by game scoring can be explained by variations in HR as a percentage of hits.

Yeah, it was an additional finding on a relatively dangerous police chase.

Since I have a pretty good beard at the moment, I should make it into an Ambrose Burnside beard for jury duty and have the lawyers assume I'm like one of those sovereign citizen people and not worth the hassle.

Hmm, in my good judgment, I don't want to wear long pants if I don't have to on an 85 degree day.
Hey @craigcalcaterra.bsky.social, am I going to get berated by a judge if I wear khaki shorts as a juror? Unlike other court systems, I can't find anything explicitly saying I *can't*.
