The Yeo first receiver thing is just an evolution of the way the game is played now.
There is any number of 13’s in the game who get the ball as first receiver there not necessarily play makers as such it’s just a means to an end, giving the actual play makers a little more space wider of the ruck.
Yeo is just a great footy player, not because he is a playmaker if that’s what you believe, it’s because of his drive, determination, commitment etc etc.
One of our greatest players ever, the whole playmaker thing thou is a little unrealistic it’s just part of the overall game plan and tactical set up.
