Cam Neely was a solid prospect when the Bruins acquired him from the Vancouver Canucks prior to the 1986-87 season.
Once Neely pulled on his Bruins' uniform, he became one of the most explosive power forwards in the NHL. Neely was a dominant goalscorer and one of the best fighters in the league. He scored 36, 42 and 37 goals in his first three seasons in Boston.
Neely took his game to another level in 1989-90, scoring 55 goals, and he followed that up with 51 goals the following year.
Neely was flying high, and when the Bruins met the Pittsburgh Penguins in the 1991 Eastern Conference Finals, the Bruins won the first two games of that series. In the third game, the series turned around when Penguins defenseman Ulf Samuelsson hit Neely above the knee and knocked him out of the series.
Specifically, Samuelsson's knee hit Neely's thigh (source: SI.com). The damage to the muscle was so bad that it started to calcify. Additional cartilage damage attributed to the blow kept Neely on the sidelines.
Neely played just 22 games over the next two seasons. However, when he came back in 1993-94, Neely was explosive. He scored 50 goals in 49 games for the Bruins.
However, the pain of the injury caused him to miss about 40 percent of the games on the schedule. He played two more seasons, but he never played as many as 50 games after that.
