The short answer is yes. Most of your problems relate to how your team is functioning in the press.
A quick stat analysis tells you you’re getting walloped on the boards and only just barely winning the turnover battle, so you’re getting killed on the possession game. You want a couple of those PFs who are sitting in the 50s rebounding to become good rebounders, up into the 70s and 80s, that will help. More importantly for press though, most of your guards are too slow for an effective press. 17 TOs per game isn’t going to get you there with a straight press. Good press teams will get 20+, the elite ones are pulling closer to 25.
At 75 your team stamina isn’t bad for a non-FB at first glance, but there are balance problems. A guy like Walters is a great zone C, for example, and a very good man C. But in a press, he’s a bench player. He can’t give you more than ~16 good minutes, unless you’re slowing down. And if the other team is playing FB or uptempo, even that will get him in trouble. He’s getting too many minutes, my guess is if you dig into the game log pbps, you’re going to see a lot of yellow and red where he pops up in the lineup in the last 10 minutes of halves.
