What I noticed with Gus, especially towards his end time at Penrith. Gus had a habit of falling deeply in love with a player, and at times overpaying for said player.
Then after the first blush of love and lust recedes, he falls out of love with said player.
So it's emotional roller coaster. That's not great when it comes to stability and forward movement of players within an administration.
Merrin, along with RCG, Blake were good examples of this.
Also his tendency to meddle into the coaching field. Happened here at Penrith in later years, happened at the dogs, and will continue to happen.
The Merrin effect appears to be happening with Fox.
(this is just my personal opinion)
I believe clubs work better when less emotion is involved.
