My recollection is that we specifically kept Rob off of physical bigs like Giannis and Embiid so he could help from weakside. Grant and Horford did the heavy lifting as the first line of defense. If Rob picked up the assignment, it was generally just for a possession or two at a time (and it was generally ineffective as well).
I do think we need another guy who can handle that matchup physically, given that Grant is gone and Horford is old. I don't want to overburden Tatum, and I don't think Zinger can handle that over an entire series. Jamychal Green and Bismack Biyombo appear to be solid candidates and are still available afaik.
I'm no expert on Oshae Brissett, but this is where he's just so critical as the roster stands right now. 6'7, thicker than most wings or at least thick enough to play power forward minutes. Here was the scouting report on him:
Defensively, the Pacers were better with Brissett on the court than they were with him on the bench. Opponents scored 3.4 fewer points per 100 possessions with Brissett on the court than with him on the bench. That number ranked in the 80th percentile in the league, per Cleaning The Glass. In addition, the teams Brissett’s played on have played better defensively per 100 possessions than they have without him in three of the four seasons in his career.
He's a hustle guy who hits some corner threes, I guess, and has a 6'11 wingspan. He measured at the combine at less than 3% body fat. So he's long and strong, and hustles a lot.
He's not going to stop Giannis. Neither was Grant Williams or Rob Williams or anyone else, really, other than Al Horford a little bit a couple years ago when he wasn't this old. But he's going to be the guy we throw at the problem and hope he's annoying enough to bother Giannis.
Same with Lamar Stevens. 6'6, 230 pounds.
He quickly became known for his tenacious work ethic and his relentless defense. This earned him a multi-year contract in 2021.
The plan is for guys like Brissett and Stevens to just kind of get in the way, make Giannis work, and then have Porzingis there at the rim to make life harder. That's a lot of pressure on Brissett and Stevens, but it's not crazy. I haven't really watched him play much so I'm excited to see what he's got.
It's the Semi or Grant plan but with Zinger behind them instead of Rob.
