    Gavin (inferred) calls Kessler the best rim runner Luka has played with (with a nod to Dereck Lively). He says the Lakers paid a steep price for Kessler but he might be worth every penny, and that many of Kessler's points came on Luka lobs.

    J-Mac said Walker Kessler gives the Lakers a rim protector, as Dereck Lively II did for Luka's Dallas Finals team, and that Kessler, 'when healthy,' is one of the league's best rim protectors.

    • Max Christie sat out this game, which the hosts attribute to rest. Santi Aldama and Dereck Lively are both still out. at 11:16
    • Lively is the team's only game-changing defender, but the hosts say he can't realistically be counted on to play games. Rookie Morez Johnson might grow into that role, but that's a lot to ask. at 16:37
    • Rebounding: Dallas won the first-quarter offensive glass 7-2 and second-chance points 13-2. Atlanta's guards and wings then outrebounded them 15-5 on the offensive glass, which the hosts link to players leaking out early. They worry about rebounding without Lively. at 28:58
    • Santi Aldama and Dereck Lively both remain out. The hosts say Lively's return timeline is unknown. at 11:17
    • The hosts call Lively the only true game-changing defender and the team's intended defensive safety blanket, but suggest he can't be counted on to stay available. at 16:37
    • Lively is the roster's only true game-changing defender, but his absence is open-ended ('who knows how long'). at 20:22
    • Santi Aldama and Dereck Lively II are still out. A host later said there is no Lively 'for who knows how long'. at 11:17
    • A host is concerned about rebounding without Lively. He wonders whether playing too fast and leaking out is letting opponents crash the offensive glass too easily. at 28:52
    • A host says Dereck Lively II is the only roster player who is a game-changing defender. at 20:22
