I guess the thing that he has on Crosby is height. Those extra two inches might be the key to domination
He's grown a lot over the past 18 months, but his growth from maybe Jan 2014 to the summer was IMO the most significant. He looked to had grown ~1 inch from the 2014 WJC to the 2015 WJC camp.
His body type and athleticism reminds me a lot of Stamkos / Gaborik / Malkin. Wouldn't be surprised to see him scare 6'2 205 lbs, though that might be a stretch (ha that's punny). Crosby grew another half inch or so after being drafted.
Its really amazing the think about how far the league has come in the past 10 years since Crosby. If McDavid could travel back in time to 2004/2005, its very possible he'd be seen as the better prospect. The toolset he brings is just so outrageous, he is definitely more skilled than Sid at 17/18.
- He's faster - will be a top 5 fastest skater in the NHL immediately
- He's got quicker hands - Crosby had ridiculous hands, especially in tight, but McDavid's hands are Kane-esque.
- He's got a better wrist shot. I know its a weakness of his, but it was the same for Sid. Crosby had the better and quicker snap shot though
The biggest advantage for McDavid is in the skating and reach territory. Crosby has never been a super speedster. Both guys have just insane passing skills and vision though, slight edge to Sid.
Me personally, I'd still probably take Crosby as a NHL prospect, even when adjusting for era. And that's because Crosby has McDavid beat where it most counts. Crosby at 17 was much more powerful, had a lot better balance, had better hands and finishing in tight, and had notably better anticipation skills around the net. Crosby already played an NHL style game in junior. Gritty, strong, and around the net. He didn't need to hold onto to the puck as much as McDavid to produce.
All that said, if I was picking for ceiling, I take McDavid all day. Speed, hands, size, and vision like that don't come around too often.
