Yes, absolutely. Like I mentioned in your previous question, the blindside flanker is seen as one of the hard men of the team. You literally have to be a human wall, nobody gets past you. Hit hard and make them scared of running at you.

Of course. In fact your principal job is to make tackles and generate turnovers.

A flankers job is to be a work horse and just be everywhere on the field. You must be very fit for the position. at scrums you must harras the halfback and first five to make them drop the ball. You must also read the game well and be at every ruck and maul
