You don't exactly need to defend pick-and-roll threats in the PBA as much. Plus, Ginebra has Japeth and of course Brownlee. I think the better case would have been the Asian Games. Ange was our closing center in the knockouts because June Mar was a defensive liability. Like sir Rds said, defense won us that Asiad.
I mean, even in the February 2023 window, where JB and June Mar started together, JB couldn't really cover for June Mar there, and was better off being the center in a small-ball lineup. Cone was already our defensive coordinator. We won against Lebanon that window because we out-shot them, and we lost to Jordan because of a big deficit thanks to poor defense early (we were down by 19 after the 1st quarter; Brownlee had to play almost the entire 2nd half at center). Well, this game kinds of illustrated why Brownlee fits so well. He can anchor our defense as well as carry the scoring load.
As for Tab, he had Dwight, Navarro, and Baltazar on his team in addition to Ange, playing roles similar to Oftana and Newsome. Perez is prone to blow-bys and likes to play the passing lanes. This is where a safety net behind is key. Still need good defenders at the 4 and/or 5 positions to cover.
