Was the Duane Brown trade the first sign of the end times?

Disclaimer: I'm not arguing over whether Duane Brown should have been traded or whether the organization had a choice in the matter. There's clearly 2 sides in this sub where one believes management and the other doesn't.

What I am asking is was this the moment where the team started its current spiral into the current bleak state? As a refresher, Duane Brown was traded for picks that turned into Martinas Rankin and Lonnie Johnson. Rankin was then flipped for a Carlos Hyde 1 year rental and Lonnie Johnson is hardly even playing and appears to be without a position.

Just thinking about this trade in hindsight really irks me considering it spawned the Tunsil trade which is looking pretty terrible considering our lack of draft picks and the new narrative that we can't keep players because we had to max out Tunsil. Brown is obviously not a top tier tackle, but I think I would rather have him and our draft picks plus cap space than Tunsil if there had been a way to make amends. Brown is currently the 17th highest paid LT in the league which is in line with where he ranks in my opinion.

Anyway, if I had to point to a moment in the BoB era where the roster building turned south, I would say it was the Duane Brown trade. Anyone else have a better moment that showed the beginning of the demise from a roster building POV?
