Just curious why you think that? Morrow is more of a low post player only whereas Jacobson has more outside range to go along with his low post presence.
That's just my opinion I formed based on his size and watching him throughout the season. There were times he looked great playing the 5, so perhaps my opinion would be different if Morrow was playing healthy the entire season. Either way, we need to add Jordy to the roster next season.
