I think it's likely the Rangers add a very key component, likely at forward, at some point. They appear to have a good track record of developing and selecting depth options for themselves. Berard, Othmann, Cuylle, Edstrom, Sykora, McConnel-Barker, Chmelar. Mancini, Robertson, Scanlin, Emberson appear to be good defensive depth. They have Laf, Kaako, Chytil, Zibanejad as long term core pieces up front with Miller, Schneider and Fox on the back-end.
If it's not McDavid, it will be someone. Kaprizov is intriguing as well.
