Styles make fights and basketball personnel changes the playoff series.

After dusting off the Hawks last week, the Knicks face a much different type of challenge in Round 2 against the Sixers.

For this matchup — which begins Monday night at MSG — the biggest threats to New York are at center (Joel Embiid) and, especially, at point guard (Tyrese Maxey).

Philadelphia’s stars are two very different types of players who pose matchup problems and combine for a potentially lethal pick-and-roll attack. On the other side, the Knicks should have their own pick-and-roll advantage with Karl-Anthony Towns and Jalen Brunson.
