Gretzky said he is especially impressed with McDavid, taken by the Edmonton Oilers with the No. 1 pick in the 2015 NHL Draft, and is eager to see what the 19-year-old forward can accomplish.
"He embraces the pressure; he's under the microscope and it doesn't seem to faze him whatever," Gretzky said. "He just really plays hard every night. Unfortunately for him he got injured (McDavid missed 37 games with a fractured clavicle); if he hadn't been injured I think he would have racked up a lot of points. He's got a lot of hockey ahead of him, a lot of years to go, and he's going to be wonderful for the Edmonton Oilers and the NHL."
Gretzky, a 10-time Art Ross Trophy winner as the NHL's top scorer, said he also enjoys watching Chicago Blackhawks forward Patrick Kane, the player who's likely to win the scoring title this season.
"Patrick Kane has had a real special year," Gretzky said. "It's really been remarkable, what he's done and what he's accomplished. There's no question he's had an MVP banner season. He's fun to watch and he's an exciting player."
Gretzky will captain the Oilers alumni team that will play a team of former Winnipeg Jets on Oct. 22 as part of the 2016 Tim Hortons NHL Heritage Classic.
"I don't know how good we'll be, but we're all looking forward to it," he said. "I've talked to a bunch of the guys already to see who wanted to play, and we pretty quickly put together 15 or 16 guys pretty rapidly."
