Here's another example of how we're unable, as fans, to consider every angle. I'll make it fairly rudimentary for brevity's sake.
Say that, in film preparation, Waldron identifies that an opposing safety is prone to biting on an underneath crossing route to take it away. He may decide, therefore, to call a couple of crossing routes that are ultimately unsuccessful.
This'd piss us off, because we'd say "Hey, Waldron, that shit isn't working. Dumbass." His goal, in this case, wouldn't be to simply call a successful play. It'd be to set up a shot later where the offense can take advantage of that tendency. Start by reinforcing the thought in that opponents mind that the tendency is correct, and then dial up a shot that earns a gain off of the safety biting.
That would be context we don't have that exemplifies rational thought behind the playcalls we may deem unimaginative or ill-conceived.
My issue is on a macro level, and this isn't a defense of him, per se - but it's not going to be as simple as "we have dumbass idiots, and other people are not dumbass idiots."
I try to acknowledge this in my posts, outside of the gameday forum. The amount of high-level nuance that goes into this is frankly impossible to imagine. This is why I don't like easy answers like "Pete's dictating all of this" or "There is only one issue with this team and it's -insert coach-." Occam's razor is not an applicable thought principle when your inside knowledge is as limited as that of a fan.
Football organizations are leviathans.
