Young forwards develop their offensive game quickly. Gretzky's scoring increased by 18 percent in his second season and Crosby's 120 points were 21 percent more than he had in his first NHL season, so if McDavid remains healthy, it's not unreasonable to expect his scoring to increase by the 17 percent required to reach 102 points in 82 games.
A closer study of his scoring totals with Erie of the Ontario Hockey League reveals how quickly McDavid's offensive production can improve. Using modern metrics to convert his OHL scoring to an NHL standard, McDavid's scoring increased from an NHL equivalent of 0.33 points per game at age 16 to 0.56 at age 17 and 0.80 at age 18, and then 1.07 with the Oilers at age 19. Based on that trajectory, the necessary increase to 1.24 points per game is within reach this season.
As a working example of McDavid's potential to increase his offensive numbers, compare his performance prior to Nov. 3, 2015, when he broke his left clavicle, to his scoring rate after his return on Feb. 2, 2016. His scoring increased from 0.92 points per game (12 points in 13 games) to 1.13 points per game (36 points in 32 games). That's a 22 percent improvement.
Another reason to believe McDavid will increase his scoring is the likelihood that he'll get more ice time. He averaged 15:08 of even-strength ice time per game last season, fifth among Oilers forwards. Imagine what his scoring totals would have been if McDavid had the same amount of ice time as Kane, who led Blackhawks forwards with an average even-strength ice time of 17:14 per game.
On a per-minute basis at even strength, McDavid scored at a higher rate than Kane. With 34 even-strength points in 681:18, McDavid averaged 2.99 points per 60 minutes at even strength, compared to 2.93 for Kane, who had 69 points with 1,413:30 of even-strength ice time. This means that an increase in playing time could be enough for McDavid to win the scoring race, even if his scoring rate doesn't improve.
There's every reason to believe that McDavid will be given a chance to lead Edmonton's offense this season. Taylor Hall, the Oilers' scoring leader in three of the past four seasons, was traded to the New Jersey Devils for defenseman Adam Larsson on June 29. The Oilers also signed unrestricted free agent left wing Milan Lucic to a seven-year contract July 1; that should provide McDavid with the big (6-foot-3, 233 pounds), crease-crashing linemate he will require to maximize his scoring at even strength and on the power play.
