The comparison was because McDougall had all the physical aspects required to be a quality forward barring perhaps strength. However, his athletic ability masked that. Unfortunately he had the heart the size of a pea.
I'm not suggesting Grover has a pea-heart but he MAY NOT have the mental capacity to play as a gun forward.
Now why don't you act mature and play the ball, not the man. You haven't come close to addressing my points. I assume that's because your evidence ends at "I have a hunch"
There is no comparison. One is a player who did it the hard way and is 4 games away from playing 150 AFL games, the other is a pretty boy chump who conned a packet out of two clubs by doing nothing other than looking the part.
To address your points -
1. Height - Grover is 4cm shorter than the best KPP in the league. He's used to playing out of his weight division as a backman. There is no reason he can't transfer that to the forward line.
2. 'Cherry picking' - he is a very good mark and 99/100 chooses the right option between a marking attempt and a spoil. He is a very strong mark and rarely, if ever, drops one.
3. Kicking - you really do seem to have a problem with comparisons. Lynch? Really? Grover's kicking is fine. It's not elite, but there is nothing to suggest it won't be good enough for him to slot most shots through.
4. Creativity/Timing/Playing in a forward setup - he doesn't appear to be as creative as a McPharlin type, but that is simply due to his position. He is not afraid to run off his man and venture forward when the opportunity presents, but when you're spending your days minding the best forwards in the league, you've usually got other things to worry about. Has spent time in the middle also, which suggests his creativity is not completely absent.
Timing I would have thought was an important skill to have mastered as a backman. Same with judgement. If you lack either or both, it's will cost you big time playing against players like Lloyd and Fevola.
Playing in a forward set up - he's played as part of a team in the backline for years. I'm sure he's capable of learning a set play or two.
5. Mental capacity - do you have any idea who Grover is? What would even make you consider that he may lack the mental capacity to play as a key forward? Everything he has displayed in his 146 game career has suggested that he has a tough, uncompromising, never say die attitude.
