Until Monday, Middleton had only gone as far as playing 4-on-4 full-court, so this is a clear advancement on his path to playing in a regular-season game. “He’s good,” Bucks coach Doc Rivers said in his pregame media conference. “He’s not ready to play yet, but he’s working hard. He’s gone through 5-on-5, we’ve done some of that. The next steps are getting on the floor, but I can’t tell you when that will happen. “I don’t know if it’s a step forward or a step that we planned; 3-on-3, 4-on-4, we’ve been doing 4-on-4 full court for a week, so I don’t know what the difference is. We added a guy, so I wouldn’t make that big of a deal about it. The key is we’re just trying to get him back on the floor and he’s gotta go through the process.”
