Bucks general manager John Hammond said adding size will be a priority during the offseason.
"You talk about the Brandon-Monta combination; it's an extremely young backcourt," Hammond said. "I think they're both willing passers, and they both also have the ability to score.
"Is the size a factor for us? Of course it is. It makes it difficult for Monta. If you're going to go with the old theory, one of the best ways to keep a great scorer occupied is to keep him occupied on the defensive end of the floor, wear him down defensively.
"He (Ellis) is a 20-point scorer at the 2 guard spot, but a lot of times he's guarding similar-type players and they're bigger than him. So if you look at the needs of our team, if there's an opportunity to get more size in the backcourt, that possibly could help us."
Scott Skiles also pointed to the Bucks’ small lineup.
"We need size everywhere," Skiles said. "Most games, right at the jump ball, when you look at the two teams, the other team is noticeably bigger than us at almost every position on the floor.
"It's just something that has to be addressed. The guys know it, too. They know we need to get bigger."
