Well, let's break it down:
Your premise is:
1) The O-line loves, and respects Tyrod Taylor, and believe that he should start vs. the Chargers.
2) McDermott benches TT in favor of Peterman.
3) The O-line is angered by this decision, and decides to not offer Peterman the protection that their jobs require. (Hey, they don't care WHO starts. It could be JOE BLOW for all they care! As long as it's not Taylor, they're not going to do their jobs!)
4) The game starts, and to plan, they ignore Peterman's leadership, and go ahead and let Joey Bosa, and the Chargers' defense destroy Peterman's first NFL start.
And, you don't think this reflects poorly on Peterman's leadership in any way? For real???
Talk about embarrassing! Do you not see how astonishingly stupid this narrative is???
(Jesus, am I a fish on a hook, or what?)
