[3] The Rangers defense lost their gifted-defenseman, Brad Park due to a knee injury that occurred on 11/15/72 against the Flyers, which forced him out of the lineup for the next 18 games.
So, on 11/28/72, they settled on veteran defenseman Ron Harris of the Flames who had minimal offensive skills but played a physical checking game.
A 26-year-old forward, by the name of Curt Bennett was still scoreless with the Rangers while mostly sitting on the bench, so he was sent to the Flames in exchange.
Harris was instrumental in winning key games for the Rangers in different ways such as: against the rival-Bruins in game #2 of the 1973 playoffs, he threw a legal, rolling, hip-check at Phil Esposito which injured him, thus, sinking the hopes of the Bruins since they lost that playoff series; plus then, in a key 1974 playoff game against the Canadians, Harris scored the game-winning goal in overtime which eventually sparked the Rangers in winning that playoff series.
Likewise, the Flames cashed in on Curt Bennett since he finally and quickly matured with them by becoming an excellent goal-scorer and their toughest fighter.
