agree he has been awful on the pp but ANY skilled player will tell you that getting easy touches on the pp and handling pucks and such during a game will roll over into a level of confidence at 5v5. there is no guarantee that it will happen with him but at some point he or kakko needs to get an extended look
Sure, for Kakko, I would buy that. I don't know if an "easy touch" exists for Lafreniere.
It doesnt make him good as a 5v5 player if the whole team was shit 5v5 and he was the best of the shit. the guy would torch bad defensive teams but anyone with awareness would know he would either come down the left and make the hard backhand pass high slot or curl to the boards and try to find a trailer. He was horrific with turnovers on his own side of the red line as well. I am not sure how you quantify "best forward 5v5"
He would be one of the better ones on a any team. He's still extremely effective 5v5.
He had 56 even strength points despite his worst shooting luck year as a Ranger and he drives play in the right direction on both ends of the ice.
Even the last two years, which are the years he allegedly sucked, he's 13th in the NHL in 5v5 points. Since he joined the team, he's 6th.
The criticism of his performance in the playoffs is valid. The criticism of Panarin as an even strength player isn't founded by anything. Honestly, I don't even know where it comes from.
I think he's just really good on the powerplay and some people just don't like some of his habits, and the myth grew from there.
