Bucks coach Doc Rivers wasn’t sure it was a good thing that Giannis Antetokounmpo scored 22 of the team’s 24 first-quarter points Wednesday night. But Rivers could smile about it after Antetokounmpo finished with 59 points in the Bucks’ 127-120 overtime victory against the Detroit Pistons. It was the highest total by any NBA player this season and five short of Antetokounmpo’s career high of 64 set last season against the Indiana Pacers . “I’ve seen a lot of great games as a player. Sitting next to Dominique [Wilkins], you obviously see a lot of great games,” Rivers said, referring to his former Atlanta Hawks teammate. “It’s funny how a coach thinks, though. We called a timeout and Giannis has 22 of our 24. This ain’t good. I’m thinking the exact opposite. We’ve got to get somebody else involved in this. “After the game, you realize how special this is. But during the game you’re in a panic.”
