#10 Indiana Pacers - Record: 39-25

The Indiana Pacers sit 5th in the East standings

The Indiana Pacers embarked on a dismal run of form back in February that resulted in the team falling to seventh in the East standings. However, Nate McMillan has been able to turn things around over the past month, and following a run of eight wins in 10 games, the Pacers sit 5th with a 39-25 record. Victor Oladipo is starting to find form following his return from injury - and the Pacers have huge games to come this week against the Celtics and Sixers.

#9 Miami Heat - Record: 41-23

Jimmy Butler and the Heat have struggled since the turn of the year

Following weeks of disappointing results, the Miami Heat have won five of their last six games - including a huge midweek win over the Bucks. Miami restricted Giannis Antetokounmpo to just 13 points during the 105-89 victory, and Erik Spoelstra will be confident that his side has now turned the corner ahead of the business end of the regular season.

The Toronto Raptors continue to surpass expectations

Following a run of three consecutive defeats, the Toronto Raptors rediscovered form over the past seven days by picking up wins over the Suns, Warriors, and Kings.
