Yet during TI, OG was encouraged mostly by his fans as n0tail aknowledged.
And if you look reddit trends (as there is not hltv like dota2 community like as far as I know) a lot of people consider him a the real MVP. And if you watch the film made by Valve (the one I linked) you might reconsider your thinking about him looking how he coached his team during the event.
Also, even the legendary german named Kuroky acknowledge him as one of the best drafter/analyst to draft against.
So I dunno about when he was desk analyst, but your comment seems kind of exaggerated to me.
