Despite Jack's shortcomings, he is still a very quick straight-line skater, and he picks up speed quickly. He has a quick burst and moves in a way that can be compared to Nikolaj Ehlers. He also can gather a loose puck and gain control of it with his stick handling skills, not losing too much speed off the rush when he receives a pass. From a pure skill point of view, he can also land passes on his teammates' sticks accurately, although he has a tendency to force passes and handcuff teammates sometimes when he is under pressure.
From the defensive zone, he can carry the puck up the ice and bring it past the offensive blue line. Zone entries are his best contribution. However, he requires significant puck support from his teammates to maintain possession once he has entered the zone; he does not pressure the opponent along the boards well, nor does he generate dangerous scoring chances upon entry at the U20 level -- most wide rushes get pushed all the way to the corner, at which point he has no angle to attack the net off the rush. Sometimes, he tries to do too much by himself with the puck on his stick and gets stripped of it.
On the powerplay, when he has time to maneuver in the offensive zone without pressure, he doesn't force plays as much and instead tries to take his time moving along the outside to create a scoring opportunity. He has enough room to think and operate on the powerplay at the U20 level. At even strength, there's just not enough time or space; he does not control the pace.
He is quick and nifty with the puck, but falls short in other areas.
