For the record straight, both are two of the greatest players in their generation and arguably their franchises as well. However, since they both have been dominant for so long, in the same division with multiple playoff matchups against each other, and coming into the league just a year apart, they are one of the biggest player rivalries in hockey amongst hockey fans.
However, these two do not view themselves as rivals and are actually good friends. Anytime they go head-to-head, they are always friendly and have even had the opportunity to play together during All-Star Weekend.
Head-To-Head
When two of the best go head-to-head, Sidney Crosby has the advantage as he is 39-23-4 overall with 88 points, which is 26 more than Alex Ovechkin.
