Johansen seems to be breaking out and the Rangers' offense has come alive.
There's a good chance Hagelin will be playing with both Richards and Nash (once he returns), and Johansen was finally given some good linemates to work with in the last game I saw CBJ play (he put up 3 pts playing with Dubi and Atkinson).
It's really a toss up. I think both will have around 45-50 points by season's end. Hagelin will have the better +/-, in all likelihood, though, so let that be the tiebreaker if that counts for points in your league.
