I'd be shocked if he's ever a 2nd liner. A guy like Vesey was more productive and topped out as a mediocre 3rd liner. That's probably more the type of upside you're looking at from Meyers. I don't think it's all that worth it.
Devils are organizationally thin at center, especially for the bottom 6. Boqvist shows flashes, but we're not sure the consistency is there yet. McLeod is a serviceable 4th liner, especially with his face-off competency. Both of these players inject speed into the line-up, which is nice, but I'm not sure I'd be willing to commit to either of them yet as long-term options for the bottom 6.
Meyers would, if nothing else, give you another name to throw into that hat. If he's at least as good as Boqvist or McLeod -- which is conceivable -- he gives you more depth. With Zacha a likely trade candidate for the off-season, there is not a lot of flexibility if the Devils suffer an injury up the middle.
In the prospect pool, the Devils are barren. Pytlik's injuries have slowed his development to the point where you can best hope he's a future 4C, and he's the top center option in the pool right now. If you consider Salminen a center -- and I don't -- his stock is certainly down after the Devils reached for him a bit in the 3rd round last year. Shlaine is maybe an AHL guy, and Baumgartner was a wasted pick who could probably no longer be considered an AHL prospect, much less an NHL one. Zakhar Bardakov was probably the Devils best pick after the 1st round last year, but we're still not sure if he projects to center or LW.
All I'm saying, is it might make sense for the Devils to take a run at an almost NHL-ready 23 year old who might represent the best center UFA option out of the NCAA this year.
