I'm pretty skeptical of Draisaitl's ability to carry a team without McDavid by his side, and he definitely has not proven it thus far. But Aho is being quite overrated in this poll.
Aho's past 3 seasons: 1.94 P/60
Draisaitl's past 3 seasons without McDavid: 1.77 P/60
Given the discrepancy in quality of teammates, I honestly think LD's production is more impressive here. Granted, Aho is trending upwards in this department while Draisaitl is trending down, but Draisaitl's team was such an absolute tire fire this season that I'll give him the benefit of the doubt here.
Neither player is anything to write home over defensively.
