The chart shows the running 62-game average scoring production for Crosby, starting with his rookie season in 2005-06 (left) all the way to his current scoring rate (right).
This graphic shows that Crosby's current scoring rate of 79 points in 62 games under Sullivan actually takes Pittsburgh's captain back to his career average, not to new heights. With the exception of his rookie season and the period immediately prior to Sullivan's arrival, Crosby has always scored at this rate, or better.
Crosby began his NHL career as a point-a-game player early in 2005-06, and his scoring rate quickly ascended to its first peak of 110 points in 62 games, from March 24, 2006 to Feb. 4, 2007. He ended the 2006-07 season by leading the NHL in scoring, winning the Hart Trophy and Pearson Trophy (now the Ted Lindsay Trophy), and being named to the First All-Star Team.
Crosby's scoring then settled back to its standard pace of about 80 points per 62 games for five seasons before his second peak of 108 points in a 62-game span from March 24, 2010 to March 20, 2012. This peak lasted two more seasons, 2012-13 and 2013-14; during that time, he was named to the First All-Star Team and won the Pearson Trophy each season and the Art Ross Trophy as the NHL's top scorer in 2013-14.
Mike Johnston was hired as Pittsburgh coach before the 2014-15 season; his systems, combined with some injuries and bad luck, led to Crosby's first scoring drought. His offensive production dropped below his previous standard, falling to a career-low of 51 points in 62 games from Jan. 20, 2015 through Dec. 5, 2015, seven days before Sullivan was hired.
At the time, Crosby was 28 years old, and it appeared that his time as the League's most dominant offensive player was coming to an end. In general, offensive production doesn't decline until a player enters his 30s, but every individual is different, especially those with a history of concussions and other injuries. In this case, such speculation was premature.
Sullivan's arrival immediately rekindled Crosby's scoring success, which has returned to his established levels. Not only can he continue to score at his current pace, but Crosby could continue to climb to his third and greatest career scoring peak and his second NHL 120-point season.
