While the NHL hasn't officially announced plans for more teams, NHL player agent Allan Walsh recently shared his thoughts that expansion is on the horizon. During his podcast, Walsh confidently predicted that not just one but two new franchises would be joining the league in the future.
Should the NHL officially expand, it's likely Quebec City, Houston, Kansas City, Portland, and Atlanta for a third time would be the top candidates.
Given Walsh's deep connections in NHL circles, his confident prediction likely means we could see these changes happening sooner rather than later.
