Flames lost a top prospect in Erixon to the Rangers. Will step into their line-up next season.
Just because he may be ready to enter the Rangers lineup doesn't meant that he will. The same thing was said about Ryan McDonagh and he spent half a season in Hartford. Erixon will get a chance to battle for a spot in training camp, and if he plays well, he will get it.
The Rangers are stocked with defensemen and it allows the team to let other players develop into players or better trade chips. Erixon has played against men the last few years in Sweden, so he has experience with that to draw back on as he transitions to the NHL.
