I gotta be honest with you, my concern right now is how he thinks through the game.
In so many ways he feels like he's on the opposite end of the spectrum from a guy like Andersson.
Obviously different players and different positions, but just feel like they're approaching from two different directions.
Andersson isn't a guy whose skills immediately jump out at you. He isn't a physical speciman, he isn't flashy, he's not really who blows you away with any one particular skill. But he's smart, and he knows where to be, and he makes sure he gets there and almost instinctively knows what to do. There's a certain efficiency to his movements and thought process.
Day is a guy who catches your eye on the ice. He's big, moves fluidly (moreso than straight speed), can cover a lot of ground and generates attention. But there's often a sense that he's moments from disaster, a hesitation, a slight delay as the play unfolds, or that he doesn't quite fully grasp what's happening in front of him. You tend to see if against better individual competition, or better than average teams. It's like watching a fielder who doesn't get a good read as the ball leaves the bat, but is athletic enough to get to the plays.
Because of that, you wonder how it will translate against better competition where the game is so much faster. I don't think the reads and awareness will ever be a strength, but can he keep progressing to the point where he's good enough (with his athletic ability) to make it work?
But that answer isn't going to come sooner, if it comes at all. It's going to take time and patience, and maybe even a second contract.
