I would trade Burns for a guy like Marner; keep EK65 because he's a much better puck mover and passer, and continue to work for quality young forwards if I was DW. I don't think a trade for a 1st round pick forward that's not in the later stage of their career could be anchored with a trade involving primarily Vlasic.
Several issues though. First is EK65 injury prone on the Sharks. However, getting more offensive power will take some of the pressure off EK65, and hopefully less injuries. Sharks are out of balance in terms of offensive power in two defenders (EK65 and Burns) just brings more heavy hitting, and dirty hits on those two.
The next issue is Jones, and whether he can turn it around. Ideally, DW would also find a surprising 2nd goalie that is capable of having a good year. Jones needs competition from a backup goalie that can clearly put him on the bench.
And the finally issue is Hertl, and whether he can come back and continue his climb to being a top center in the NHL. If it wasn't for Brown's dirty hit, Hertl would have been there now, imo. Couture and a Hertl back to where he was predicted to be, would be one of the NHL's notably pair of centers.
If he can pull those three things off, and the stars aline for Hertl, the Sharks should return to cup contention next year.
