But there's no better test for knowing you're in game shape and fully fit than suiting up against real opposition in real game action, and history from a broken clavicle in his rookie season tells McDavid that the first few shifts will be the beginning of a feel-out phase.
"I feel like that's any injury," McDavid said. "I came back from my collarbone, and sure you practice and whatnot and you take bumps here and there, but nothing really replicates a game. Obviously that stuff is part of the game, so we'll see what happens."
Luckily for Connor, he won't have the additional task of adjusting to new linemates. The Oilers captain will centre a line with Leon Draisaitl and Zack Kassian - a carryover from the top line he ended with last season.
"It's always good to come back and have the same linemates you finished with," McDavid said. "Drai and I have played together for a long time, Kass kind of sporadically, but we finished the year together. I'm looking to build on that."
LINEUP NOTES
A veteran Oilers lineup tonight dressed by Tippett could provide a good look into the head coach's thinking towards opening night.
Tippett took an experienced group of 31 players to Kelowna for team-building and practice this past weekend as he looks to solidify pairs, lines and roles with just over a week until the '19-20 NHL regular season gets going.
"We've got a veteran group right now," Tippett said. "Through the first four games we really experimented with a lot of people in different roles, and now we're trying to stabilize it a little bit. There are some guys that are going to play the last couple of games after this, but I'd like to get a read on our lineup."
Defenceman Joel Persson remains a player whose spot is in flux as he lines up alongside Oscar Klefbom on the team's first pairing, while also getting a chance to quarterback the first-unit power play tonight.
"I want to see if he can run a power play and the creativity he brings," Tippett said. "The right shot there, he's the one guy that we're experimenting with right now."
