Probably not.
No. Lehkonen has never been, and never will be a player who controls the play. He's an opportunist. Jesperi is much more of a player who will attempt to control the play. About similar numbers, just because someone produces similar numbers at the same time doesn't mean that they'll go on to do the same things. This applies equally to Rantanen and Aho as it does to Lehkonen. In all three cases, however, these are all NHLers of varying quality, and I'd argue three pretty good NHLers. Things just haven't clicked for Lehk quite yet. But with the amount of rubber he puts on net and his knack for scoring the comparison will become more favourable.
