That would leave you pretty thin at center, no? I realize Tavares is a stud and Ennis is doing well so far, but I mean it purely from a numbers standpoint. If you start F's instead of position players it's no problem, but you specified LW, C, RW, so that's a concern I'd have.
How would this affect your keepers? I probably wouldn't have Galchenyuk or Grigorenko as keepers for you, unless one of them overperforms big time. Ryan would probably be a keeper for you though.
I'd do it, especially if you can get a 20 point replacement center on waivers.
