I don't want Jack to have a goal scorer with him and don't want Bratt taken away from him. Jack should be the goal scorer and primary shooter. Don't give him someone to defer to as the shooting threat
Jack's shooting is creation-based, not a goals scorers shot; he 100% needs a shooter and thats exactly what Fitzgerald has been looking for to get him (hence Holtz and trying Meier there)
Also Jesper has undoubtedly always played better with Nico; he is the primary puck carrier for that line when they do, and Timo would unlock having a second playmaker instead of Noesen (love ya nose but...)
Jack will get a goal scorer this or next offseason; until then Jesper is perfectly fine for his wing, but they arent a perfect fit the way Nico and Jesper are
