I don't really see either. Tavares uses a combo of elite hands and strength on the puck to drive the center of the ice. Tarasenko is ridiculously strong and is able to hold guys off to get off his world class shot.He looks nothing like Tarasenko to me.
I'm not sure who Mittelstadt plays like. It is very hard to compare a kid when most of his game footage comes from a league where he is capable of taking on players 1 on 4 and still getting a high-quality scoring chance.
