Rosen is s a quick and energetic player, able to accelerate in the blink of an eye and burst into open space, despite the fact that he’s not the most agile and doesn’t get the best extension in his stride. Instead, he gets to where he needs to go due to his reaction time, determination, and understanding of routes than his skating technique. Rosen always moves his feet and has the ability to create space in the offensive zone for himself or his teammates thanks to his skating. What makes Rosen so dangerous, even at the SHL level, is how well he can handle the puck and take advantage of the speed he has to create scoring chances. His overall puck control is good, but not high-end and not the smoothest. He displays an above-average nose for the net, getting himself open in high-danger areas and driving hard to the net. He has a hard and well-aimed shot with a quick and unexpected release. He also shows off a strong one-time shot, getting a great deal of force behind it. He plays with a lot of pace in all three zones, applying the right amount of pressure on the forecheck while also hustling back hard to help out defensively. Rosen thinks the game quickly and plays on high alert, including lots of shoulder checks to keep track of what’s going on around him. He has a great, accurate pass and a great vision which makes him hard to defend against. That being said, his pass receptions could be cleaner and more consistent. Rosen also need to improve on his poise, as there are times where he can try to force things and turn the puck over. Especially under pressure, Rosen can rush his decisions, which indicates that his processing will need to improve. His physical play is definitely an area for improvement, as he has a smaller frame and gets muscled off the puck quite easily. He struggles when he is engaged by stronger opponents and he has issues when battling for the puck along the boards at times. Despite getting outmuscled though, Rosen never backs down, consistently jumping into these battles and fighting hard for the puck. He’s a highly competitive player with high-end offensive instincts.
