If all it took was a player like Miller to get 2OA there would be many trades.
when was the last t8me a known 2OA pick was traded outright for a player?
Off the top of my head, Milbury and the new Islanders owners wanted a rapid turnaround and dealt #2 (Jason Spezza), Bill Muckalt, and an unproven Zdeno Chara for a prime Alexei Yashin.
Devils could certainly use a guy like Miller, but giving up the #2 pick doesn't seem like the way to go.
