Cozens' NHLe, based on his 85P in 51GP in the WHL (0.27), is 37P in an 82game NHL season. That pace would be good enough for 5th among Sabre forwards (behind Eichel, Reinhart, Olofsson, and Johansson) last year. That's up from 27P projected the year before. He'll be a contributor this year and he's only getting better.
As long as we give him good support, reasonable quality of competition, and appropriate ice time, he'll be just fine.
