This is an excellent question! Across the board, with a squad more focused on speed and collective production than efficiency and possession-control, I expect some players' stats to decline a bit even though their on-floor play improves significantly. No-Mo-Iso-Joe comes to mind in this regard.
I'd look for the Joshes to be the most noticeably improved.
Still getting hacked a ton, Cap'n Smoove will play to the whistle rather than the contact, allowing him to focus on finishing plays in the paint. I expect fewer mental flameouts, save for the occasional periods when he's getting hacked in blowout situations (LD will probably have J-Pow in there instead, an option we didn't really have last year). More time on the court will lead to more offensive boards, steals, swats, and halfcourt assists, generating better opportunities for his teammates. More than any of the other starters, I'll be thrilled if he avoids spending more than three seconds of the shot clock with the ball in his hands. He does these things, and sets himself up every time no more than 10 feet from the basket, and he'll be a shoo-in as a coaches-selection All-Star this time around.
I look for J-Pow to vastly improve his shot selection (he's VERY jumper-happy -- 61% of his FGAs are jumpers and he makes less than a third of them) and commit to becoming more of a defensive disruption. When our backups are in, he must become the inside option; he's got to get in the paint and to the line. On both ends of the floor, he can approximate the energetic play we've come to expect when Smoove's head is in the game. He does this and he'll turn around his perennial bottom-of-the-barrel plus-minus ratings.
The Joshes are hometown products who want to be on the floor and impress. They'll both be under pressure to earn their time on the floor, now that Horf can slide over to PF with greater comfort, bolstered by better and healthier options backing him up at C.
