You have no idea what he's learning, apparently he laid 3 tackles inside the first 10 minutes of the game... I have no idea about the rest of the game but that's a good start.
Getting it is not a problem, he can win the ball at ground level.
Maintaining his intensity is the problem, he actually has gotten 45% of his disposals this year (AFL) in a contested situation... so maybe you've been sucked in by this group think that all he does is rack up cheap stats?
Just going by what I saw last week and what the commentators saw this week.
