The NHL's salary cap could go up to $80 million within the next four years according to Elliotte Friedman of CBC Sports. Speaking on Sportsnet 590 The Fan's "Prime Time Sports" Friedman said some within the sport expect the cap to rise to that level prior to the 2017-18 NHL season. The salary cap currently sits at $64.3 million heading into the 2013-14 season a factor that has caused the NHL free agent market to slow down since the initial rush back in July
