potential wise, schenn's potential is through the roof, and anyone who says the defense is easier to master, it really isnt, it takes defensemen years to learn the postitioning. an offensive game is all about confidence in your shot and your puck moving ability. during the latter half of the season, schenn was making tape to tape passes game in and game out, and improved his goal total from 2 to 5 playing less then 3 minutes on average then his rookie yr. schenn will be a top 3 defensive defensemen in the league on his prime, and potential 40 pt guy. meanwhile karlsson will be prolly a top 10 offensive producing defensemen, but nowhere near up top defensively. ppl need to remember that just cus karlsson did well in a shortened rookie yr and playoffs, whats not to say if the leafs make the playoffs that schenn plays dynamite. its to early to call,but schenn will be the better player.
