The Grizzlies preseason just started, and by Sunday morning it will be more than half over.

A tale of two Media Day scrums: Jaren Jackson Jr. sat encircled, with microphones, recorders, and TV cameras surrounding Castle Jackson like an impenetrable moat. He held court with a big smile, talking about rap albums and Netflix shows, essaying the locker-room generation gap for which he’s the poster manchild in a manner that tiptoed the line between guileless and knowing.

The Grizzlies made their preseason debut Tuesday night in Birmingham with a 131-115 loss to the Houston Rockets. Scores don’t really matter in the preseason, but here’s a chain of thoughts on things that might:

On Oct. 19 at FedExForum, the Memphis Grizzlies will tip off a new season against the Atlanta Hawks. At that moment, with ball and anticipation in the air, last season’s 22-60 debacle officially moves off-stage.

The final dance contestant was Yuta Watanabe.

Marc Gasol in the kitchen. Mike Conley making Christmas mischief. Jaren Jackson Jr. in motion. A title around your waist.

The best moment of your rookie season and the worst? This is the question before the Grizzlies’ Dillon Brooks and he goes straight to his personal tire fire.

Editor's Note: This is the first in a series of five Grizzlies roster previews. Other stories will appear in the coming days.

Jaren Jackson Jr. was hanging out in the Grizzlies locker room. This was not long ago, before an informal workout. Marc Gasol walked in, looking sharp.

After talk comes action. On Monday morning, the Grizzlies assembled in the Don Poier Media Center near the eastern edge of FedExForum for an audience of Memphis (and Japanese) media. On Tuesday morning, suited and high-top-sneaker booted, they migrated west to the Forum practice court to assemble for their head coach.

From time to time throughout this season, The Daily Memphian will convene a quartet of our writers, veteran Grizzlies watchers all, to bat around the questions of the moment. We’re calling it Turn Four, in tribute to the play call -- translation: get Z-Bo the bleeping ball -- that Lionel Hollins or Dave Joerger would call out whenever the Grizzlies needed to settle down and get a bucket.

Pinnacle Financial Partners, the official bank of the Memphis Grizzlies and FedExForum, has signed a representation deal with the Grizzlies’ top draft pick, Jaren Jackson Jr.

Chandler Parsons’ most recent trip out of the country was not to Cancun, Mexico. Remember that hot-take social media moment, Parsons and his crew sporting “Chancun” caps for their All-Star break vacation and Grizzlies fans losing their minds?

The Memphis Grizzlies open camp on Tuesday, and in the pre-camp tradition, players, team officials and coach J.B. Bickerstaff took turns answering questions about the season.

The Memphis Grizzlies will hold their annual Media Day gathering on Monday, and will hit the training-camp hardwood the next day. Many questions will be asked amid Media Day scrums, but the most important ones won’t be answered on that day or even, fully, in the days and weeks that follow. But it’s a start.

From a competitive standpoint, the Memphis Grizzlies’ 2018-2019 schedule is the kind of unremarkable to which NBA schedule-makers aspire.

What did you do this summer?
