A while ago I had some nice experience with DR and DL but especially DR in my case, for few seasons straights my DR and I changed them every season, used to score or to assist like crazy. Why? No idea but it was funny to see them on top all the time. Actually my DR's for 3,4 seasons ended with more goals then my ST's which were pathetic at that time.

Good luck with your player and hopefully he will continue on this line.
