I feel like (and I could be wrong) the Red Wings were the first to really employ the center ice drop pass on the power play, in order to gain the offensive zone. This worked because they had a guy named Datsyuk, who could gain the zone at any speed, usually quite slow, through 3 guys... because he had tremendous vision, stick handling, and lots of sneaky passes, and defenders gave him space because they were terrified.
After Datsyuk left they continued the same play, over and over, for seasons... apparently never noticing that without #13 it just doesn't work. Was frustrating to watch because the reasons it was failing seemed so obvious.
