personally I don't think Dubas is interested in solving the lack of physicality on this team. He's nowhere near ready to admit his thought process on this subject is flawed, at least that's my take.
Hyman and Dermott back in the lineup will go a long way in terms of personnel, but the bigger issue is how players play - not what players play.
Moore, Timashov, Kerfoot- these are all smallish skill players that surface level "need more hits" analysis would say need to be replaced, but all three are quite feisty and hard to play against. We need more intensity from the players getting the minutes, not a designated thumper. We saw it in the playoffs last year.
IMO the real area of concern was in his strategic thinking, and it's two fold. Tactically I think Dubas has made good moves, and that we have the personnel to win. If you're judging solely on the mandate of tap-dancing around the cap and ice the best team possible while not jettisoning any of the young players he did a phenomenal job.
But that's the wrong mandate. Are we 3+ 1st round picks better than if we kept Marleau, got 16th overall from Colorado instead of Barrie, traded Kap and AJ, and signed Hutton/Sekera/Shattenkirk? No. I think Dubas was too married to keeping Kap/AJ, and was either coerced away from or too scared to roll the dice on letting the on paper roster suffer for a year to better the franchise long term.
