The Cleveland Cavaliers and the Milwaukee Bucks have each contended for and won titles in the past 10 years, but they have very rarely both been good at the same time.

LeBron James led the Cavaliers to four straight NBA Finals between 2014-15 and 2017-18 as they enjoyed an epic rivalry with the Golden State Warriors.

But Cleveland were tied for the second-worst record in the league the following year, with James in Los Angeles, as Central Division rivals Milwaukee came to prominence with the NBA's best record in Giannis Antetokounmpo's first MVP year.

The Bucks have since had control of the division and again lead the Eastern Conference through 30 games at 22-8.

Yet now there is a challenge from the Cavs, who are a competitive 21-11 and have won four straight games ahead of hosting the Bucks on Wednesday.

Having already shown real signs of progress last year in reaching the play-in tournament, Cleveland have kicked on again after a trade for Donovan Mitchell that they hope will turn them into a serious player in the East.

So far, that looks to be the case, with Mitchell's career-high 29.3 points per game leading the team – and ranking eighth in the NBA – while he has produced in big games against the Boston Celtics.

The Cavs are 2-0 against the second-placed Celtics this season; however, they are 0-2 against the Bucks, who will be intent on batting away their division rivals ahead of Christmas.

PIVOTAL PERFORMERS

Cleveland Cavaliers – Jarrett Allen

The Cavaliers will hope the physicality of Allen can be the missing piece against the Bucks. He has played only 12 minutes against Milwaukee so far this season, absent for the first game and withdrawn injured in the second having scored only a single point.

Since returning from that hip injury earlier this month, Allen has averaged 14.9 points and 9.3 rebounds, with 26 rebounds across his past two outings.

Milwaukee Bucks – Giannis Antetokounmpo

Nobody likes playing against Antetokounmpo, but only against the Brooklyn Nets and the Utah Jazz has he averaged more points per game across his career than against the Cavaliers.

Although the Cavs have spoken of Evan Mobley having the potential to become a player in the Giannis mould, neither he nor his team-mates have a fix for the 'Greek Freak' when he is in form – as he was in scoring 38 points in their last meeting.

KEY BATTLE – Can Cavs keep focus after halftime?

Two of the Cavaliers' three worst quarters this season in terms of points differential were the two third quarters they have played against the Bucks. They represented two of Milwaukee's four best quarters of the year.

The Cavs, again on a four-game winning run, had dominated the first half of the teams' most recent meeting, up by 11 before losing the third quarter 35-10 as they were blown away by the Bucks' title0calibre intensity.

Cleveland must show they are capable of going toe-to-toe with such opposition if they are to be a genuine threat this season.

HEAD-TO-HEAD

The Cavaliers may have struggled badly in Milwaukee this season, but they won their final two home games against the Bucks last year, providing hope of another win at Rocket Mortgage FieldHouse, where they are a league-leading 15-2 in 2022-23.

The Bucks have a 130-97 all-time lead in the series, although the Cavs have a 60-53 advantage in Cleveland.
