I know this is an insider article but here is the key point.

In six games against the Rockets, the 24-year-old Roy, who fought through flu-like symptoms near the end of the series, put up a player efficiency rating (PER) of 26.0, highlighted by 26.7 points per game and a true shooting percentage (TS%) of .562. The PER was 5.2 points over his career average and two points over his rating during the regular season. And he showed a willingness to be The Man when it mattered most. Roy took 3.4 more shots per game than during the regular season, increasing his usage percentage (USG%) from 27.5 to 33.1.

How does Roy compare to other star players in their first playoff performances? Try superstar-good.

It was only six games, but Roy's first-time playoff PER of 26.0 looks mighty fine alongside the first playoff appearances for Ray Allen (23.7 in three games), LeBron James (23.2 in 13 games), Allen Iverson (22.6 in eight games), Paul Pierce (21.1 in 16 games), Vince Carter (18.2 in three games), Dwyane Wade (17.7 in 13 games), and Carmelo Anthony (9.8 in four games). (I'm leaving Kobe off this list because he was just 18 years old and played only 15 minutes a night during his first playoff run.)

In fact, Roy was so good that his first time in the playoffs affords him a seat at a sacred table. Not only did his robust PER hold up next to Michael Jordan's (24.7 in four games in 1985), Magic Johnson's (22.1 in 16 games in 1980) and Larry Bird's (18.3 in nine games in 1980), it leads the way. Does that mean his career path will follow theirs? Don't be silly, it was only six games. But Roy did prove a lot in the first round.
