I don't see that as a good fit. Both like to control the play and thread difficult passes.
Strome doesn't control play anywhere near as good as Keller until possession is already established in the offensive zone, which is what Keller is awesome at doing
Strome likes to get his shot off from around the hash marks to the top of the circle.... a place that Keller is amazing at threading passes to
Strome lacks speed for forechecking, something Keller doesn't and should make breakouts much easier for Strome's line
Strome's IQ and ability to be in the right place should make him an awesome center for Keller who's ability to find rushing or open teammates is near the best in this draft
Strome has thrived with fast puck carrying line mates his entire Jr career so far whether it be Mcdavid, Debrincat , even his short stint with Marner etc... don't see how making sure you got him one in the NHL as well wouldn't seem like a good fit... at least until he shows he can maintain his productive play without one....
