The Indiana Pacers are staring down what could be the most pivotal NBA Draft Lottery in franchise history—and if you're a fan, Sunday afternoon is going to be a rollercoaster. Here's everything you need to know to track the action and understand what's at stake.

The Pacers have a 14% chance of landing the No. 1 overall pick—something the franchise has never done. More realistically, they have a 52.1% chance of securing a top-four selection. But here's the twist: Indiana traded a top-four protected pick to the Los Angeles Clippers as part of the Ivica Zubac deal. That means if the Pacers' pick falls to No. 5 or No. 6, it goes to L.A. The Pacers can't pick lower than sixth, so the drama is real.

Only the top four picks are determined by the lottery. The broadcast reveals selections in reverse order, so if a team outside the expected top four isn't called at their projected spot, it means they've jumped into the top four—which would bump the Pacers down. For example, the Chicago Bulls have the ninth-best odds, so if they're not announced at No. 9, they've moved up, and Indiana's chances shrink.

Key picks to watch: The Atlanta Hawks or Milwaukee Bucks will hold the No. 7 and No. 10 selections (Milwaukee gets the lesser of the two, Atlanta gets the better). But for Pacers fans, the real tension starts when the broadcast reaches No. 6. That's when you'll know if Indiana keeps its pick or hands it over to the Clippers. Silver lining? If they lose the pick, they retain their 2031 first-rounder.

Pacers point guard T.J. McConnell will represent the team at the lottery, adding a familiar face to the proceedings. While draft experts generally agree on the top four prospects—headlined by A.J. Dyban—the actual order could shift dramatically depending on how the lottery balls bounce.

Mark your calendars: Sunday at 3 p.m. is when it all unfolds. Whether you're hoping for a franchise-altering top pick or just rooting to keep the selection, this is must-watch basketball drama.
