He missed last 3 months of the season. If you look his minutes he played mins equal to 24 games. 6 goals, 10 assists and 2 pens won in that time is absolutely great. Only KDB, Bruno and Kane finished with more assists but still close so if he did not get injured he would definitely end on top. In February I thought he would win POTY but that award usually goes to player from champion's team.
Players like him get free pass at defending. I mean, he is the closest thing to Ronaldinho from 03-06.
