There's an obvious need for at least on more defenceman, if not two. With all of Bonk/Dickinson/Barkey/Cowan back this season, there's no reason not to trade a few more younger players--excluding Hawrey because he likely won't waive no-trade privileges--for some defensive depth. Jenken has been fairly good, but on a championship team, you would probably prefer for him to be a number 7 as a fail-safe for injury rather than an everyday player.
Trading some volume of picks and young players (Fagan/Van Bommell/Bidgood/Gerber) for a LHD+RHD to become either a second or third defence pairing. Something like Petrovski+Jenken or Petrovski+Allen would be a sizeable upgrade on Jenken+Fagan/Spencer.
