If Anaheim is open to trading down, my guess is GMBM and Madden covet Holtz. Minnesota's GM Guerin is known to want a center in return for Dumba. Consider this scenario:
NYR - Lafreniere
LAK - Byfield
OTT - Stutzle
DET - Perfetti
OTT - Raymond
Players still available would include Rossi, Drysdale, Sanderson, Holtz, etc. Perhaps Anaheim values Dumba + Holtz (selected at Minnesota's 9th overall) over 6th + whatever add would be required by Guerin. Minnesota would have to be very bullish on Rossi (compared to Lundell, who's the next best center) for this to make sense.
Obviously next season's expansion draft would have to be considered. I also don't know how significant the + would need to be from Anaheim. Maybe Lundestrom? I don't think he alone gets it done.
