Klefbom is a raw, tantalizing talent. He has great size for a rearguard, is an excellent skater, and has tremendous natural offensive instincts. This combination of size, speed, and skill had scouts salivating over him in the 2011 draft, and many in the Oilers organization are enthused about what he could potentially become. He has work to do on his positioning, his defensive play, and generally on the finer aspects of the game, and will be given every opportunity to develop those abilities.
Staying in Sweden following his draft year, the most important thing for Klefbom is to play heavy minutes and really work on the finer points of his game. He will likely come over to North America sooner than later and projects as a top four offensive minded defenseman and a power play quarterback.
