Bomba Holds No Truck For Ruckz - Joes the Go

For those who watch him at training, how does Joe go just running and marking, tackling etc in general play/midfield?

 

I see a ruckman's role around the ground as possibly being more important than tap work/at stoppages.

 

How does he compare to say Hooker or Thurlow, when it comes to his tank, speed, agility, overhead/contested marking ability, tackling etc?

From what I saw in his games last year Joe is very agile for a tall player.

Tank isn't good though.
