KEY DEADLINE TRADES

The four first-round picks swapped — not including the two conditional selections — on Monday were the most to move on the final day of NHL trading since at least 2008, according to league figures. And no first-rounders had moved on each of the previous two trade deadline days. Those surrendering first-rounders were Nashville, Vegas, Winnipeg and Tampa Bay.
