- OHL - 2nd All-Rookie Team
Koekkoek came out of the midget ranks having attended prep school with the Notre Dame Hounds, which is the same program that developed future Lightning stars Vincent Lecavalier and Brad Richards. After posting 16 goals and 43 points in 44 games for the Hounds in 2009-2010, he was selected by the Peterborough Petes in the 1st round, 7th overall, of the 2010 OHL Priority Draft.
He struggled on a very young Petes team in 2010-2011, posting a -29 rating in 65 games. Still, his 7 goals and 23 points in the campaign were good enough to earn him a Second Team OHL All-Rookie selection. He also earned his way onto Canada's U18 World Junior Championship team where he posted a modest 1 goals and 2 points in 7 games.
Koekkoek had seized the mantle of Peterborough's top defenseman and minutes eater in the first half of 2011-2012, but a season-ending shoulder injury cut short his year after 26 games, in which he had 5 goals and 18 points. He was rated #23 among North American skaters by the NHL Central Scouting Service prior to his selection in the 1st round, 10th overall by the Lightning at the 2012 NHL Entry Draft.
A very mobile defenseman with some fine offensive skills. Hockey sense is quite good and he passes and shoots the puck well. Some leadership qualities too. Admirable work-ethic. Overall a solid all-round defenseman. (EP 2012)
"Koekkoek has size, skating ability, physicality, and an offensive game that could combine to form a player who could very well be the homerun pick of the draft." (scoutingreport.org)
"He’s very good defensively, especially while defending rushes (which can be tough). He’s tough to beat one-on-one, he’s physical, he uses his body well to rub players off the puck and he’s just a tough guy in general to play against. He’s not overly big, but he uses the size and strength he does have very well. Koekkoek is a great skater, very good on the rush, and he knows when to jump into the play and when to stay back. I’d say his transition game as a whole is fantastic. Koekkoek has outstanding vision and is a very good passer which makes him quite effective on the powerplay. He has a pretty good shot, too. With his solid defensive play, it’s safe to say he is more than capable of killing penalties, as well. A few more things that I really like about him is that he’s not afraid to block shots, he never takes shifts off and will do whatever it takes to win." (mynhldraft.com)
"Mark Seidel, chief scout for the North American Central Scouting, calls Koekkoek 'physical and smart.' He’s a smooth skater that carries the puck well enough to lead rushes up the ice, but won’t leave his team hanging at the other end." (prohockeytalk.com)
"May have the highest ceiling of any defensemen in the draft...has excellent size and a frame that can support more mass...very mobile skater, strong on his edges, and has good first step explosion...very tenacious presence on the ice, making him a hard player to go up against...makes crisp tape to tape passes...very adept at skating the puck up the ice and making intelligent reads...great work ethic...battles for position in front of his net...has a heavy shot that gets through to the net...until his injury he was logging over 30 minutes a game for Peterborough...positioning and gap control can be inconsistent, but can be corrected through coaching...shoulder injury and subsequent surgery has caused him to be a forgotten player...was willing to wear a harness and play." (firstroundbust.com)
"A very intelligent defenseman with top hockey sense. Extremely mobile and loves to jump into the attack. Has a dynamic burst and straight-line speed. Sound puck mover who makes a good first pass out of the zone when time permits. Has the skills to be an offensive threat and point producer. A very strong snap shot. Not a physical player and appears content to just tie up his check in the defensive end. Uses his smarts and skating ability to avoid checkers. At times seems hurried in the defensive zone and can be pressured into coughing up the puck. Season-ending shoulder injury in November required surgery. Before that, he had become the Petes' go-to man despite his youth. Not coincidentally, the Petes dropped steadily in the standings after losing him."
Projection: Mobile, 2nd pairing puck mover.
Style compares to: Kevin Shattenkirk" (Red Line Report)
"Slater plays the game with a combination of competitiveness and determination that helps teams win. He's an excellent skater who can close down the play very quickly and deny offensive chances when they appear inevitable. He uses his body very effectively and along with his skating, he doesn't give opponents much choice or opportunity to go around or through him. He's not punishing but it's not enjoyable to play versus him because he doesn't let up in his determination to stop you. His skating also allows him to get the puck moving ahead very quickly and very effectively and he continues to explore the offensive side of his game and try to contribute in this area as well and become a well-rounded player. His puck skills are good and while there may not be a lot of deception or faking when he has the puck, there is efficiency to his puck play. He has the ability to play lots of minutes and with that type of endurance and his size, he'll be valuable in the areas that require so-called 'heavy lifting' but leads to winning." (Craig Button, TSN)
Good skater with excellent burst. Shows good intelligence and is excellent at reading and jumping into the play. Good snap shot. Can play big minutes.
More of a leaner than a thumper, physically. Can be prone to turn the puck over when under duress. Loss of time due to the shoulder injury is a concern.
#2/3 Mobile, Puck-Moving, 2-Way Defenseman
