It's not just about goals, Grundy gets a hell of a lot more of the ball than NicNat does, NicNat is a walking highlight reel no doubt, but he doesn't do a great deal in between.
No doubt about that. At the same age has he has him m covered for stats in almost every facet except those related to forward line football and contested marking.
Comparing Grundys 2016 to Nicknats 2012 (same age)
Kicks 9 to 4
Disposals 18 to 13
Hitouts 26 to 25
Uncontested possessions 9 to 3
Effective disposals 12 to 9
Which is partly why I'm suggesting he spend a bit more time resting forward when Cox is in the team. He has the ability to be a good forward, he just hasnt spent much time there yet.
