It's about organizational depth and who can be flipped to really gain something. 4 ELC centermen affords an opportunity worth exploring, IMO.
ignoring the fact that centers can play wing... i don't recall you exploring any Ennis trades when he was playing center.
regardless, it's not about "organizational depth" until you know what you have. Trading from a depth of ELCs is stupid, when we have almost nothing established at the NHL level (aside from Myers who you are also trading).
