Could be good info. Some of these content creators do get info from players.
In terms of takes and knowledge really don't rate 'Guru', the guy doesn't have much of an idea at all. He is the old "stay one lesson ahead of the kids" teacher analogy. I remember when Da Silva was making his debut he said on a podcast that he was a gun fullback and knew nothing about him. Same with a few other players over the years. Other than the Roosters, he really knows nothing about the lower grades. Also heard from people who have meet him that he loves talking himself up, which is strange in itself.
However. there are some other really good social media pages and creators that have god insights to the juniors like "theshortball" on Instagram and for West Tigers juniors, NBWT on Twitter/X.
