Quoted for brevity. The first point is why someone should be fired. The offseason plan for the OL was flawed and incompetent. And yes, someone deserves to be fired over it.
Flipping Walker to LT was an obviously flawed plan, and most observers knew he was ill suited for it. Only the rose colored wearing fans didn't foresee his abysmal performance on the left side. Then they release him for it.
They already had 2 viable starters on the interior in Hangartner and Butler. But they were so smart they decided to move Butler out to RT.
So instead of keeping Butler and Walker where they were and were best suited, they have a failure waiting to happen at LT, an experiment at RT, and now 2 holes to fill on the interior. That's 4 question marks (5 if you include Hangartner), wheras you would've only had 2 (or 3). Dumb.
Meanwhile, they could've just drafted a better tackle and one interior guy. Smacks of someone covering their tracks for botching the Peters deal.
