Burakovsky is fine. But I think a back up plan like glencross is a good idea. If we were to get another top six player, we'd be so freaking deep. A laich burakovsky Wilson fourth line would be sweet. But I keep fearing that chimera will get in the lineup over bura if it came down to it.
Also might need to keep beagle around to get hit with pucks on the pk, but you could promote bura to third line with ward and fehr. That line becomes less shut down but would have some scoring punch
