As we saw throughout most of Philadelphia’s seeding games, the 76ers losing Ben Simmons (left knee surgery) for the season was a huge blow.
So where will Simmons' absence be felt the most?
For all the impressive things Simmons does with the basketball, the Sixers will miss him most on the defensive side.
The 6-foot-10 Simmons boasts length, size and lateral quickness that causes problems for opponents offensively because of his pick-and-roll defensive potential that’s on display most nights.
Against the Celtics, Simmons spends most of his time on the floor guarding Boston’s top scorer, Jayson Tatum.

In the four games the two teams played this season, three of which were won by Philly, Simmons limited Tatum’s impact each time.
According to NBA.com/stats, Tatum shot 31.3 percent (5-for-16) in games in which he was guarded by Simmons this season.
So, if Tatum puts up big-time numbers in this series, no one should be surprised considering the Sixers player who has consistently done the best job at defending him won’t be on the floor.
A point guard trapped in a big man's body, Simmons has speed and strength that creates matchup problems on the perimeter as well as on the post.
The 24-year-old averaged 16.4 points along with 7.8 rebounds and 8.0 assists this season while shooting a team-best 58 percent from the field.
Simmons’ shooting range has been a topic of discussion for as long as he has been in the NBA. And while it creates a different kind of challenge for the Sixers when it comes to running their offense, the third-year pro has shown himself to be talented enough to still be a high-impact, difference-maker for Philly.
Soon after the Sixers arrived in the bubble, head coach Brett Brown talked about how the team was planning to play Simmons more at power forward to better utilize his versatility and create better spacing for the team’s perimeter shooters.
Like most of what the Sixers have tried to do this season, the few times we saw Simmons in that role it didn’t work. But his absence creates an even bigger hole when it comes to playmaking.
Shake Milton has moved into the starting lineup after putting together a string of impressive performances prior to the league being suspended in March.
However, his impact was greatest as a scorer, which is different from what he is being charged with now. Milton is averaging 12.5 points as a starter this season to go with 2.9 rebounds and 3.9 assists.
No one is expecting him to put up Simmons-like numbers, but the more you watch Milton play and try to run Philly's offense, the clearer it becomes just how much Simmons’ presence is missed.
