Gray walked out of the leadership group at the end of last year. Didnt want the hassle. He hasnt gone backwards.
Boak is suffering from trying to do too much. Its noticeable that other sides shut down Boak but leave Gray alone. When we are behind he is in there trying to do so much but is usually cut down by a crunching tackle from the tagger or another opponent because he is trying to do the match winning/goal winning stuff, instead of just dishing it off to a team mate in a better position. If we had someone the size of Kennedy and sat on him, like Mitchell did on Boak, we might have won on Thursday night. Its easier to match up on 183cm/83kg player than a 188cm/93kgs player.Despite what the girls say, size always matters.

Its also why we have only closed down Goodes once (O'Shea) in the last 10 years when he has played on the ball. We dont have anyone big enough, and good enough, to do the job on him.
The rest of our leaders are either out of form and playing poorly but surviving on the gold pass and lack of depth for their spot, or only playing average rather than great footy.
