Agree with the first part. On the second part, the only issue I'd take is that Mac didn't destroy LDR's confidence (which is obviously shot), LDR did that. Failure to perform only re-enforces itself. How is Mac supposed to fix that? Yank him? Is leaving him in to try and overcome his issues 'doing to LDR what he did to Treon"?
Personally, I do think we should have yanked him - not going to undermine LDR's confidence any further. Despite my lecturing my kids to never say 'it cant get any worse (because it will)', I am looking at AA thinking it cant get worse than what LDR is doing to us.
Like I said, Del Rio should have never taken a 2nd half snap:
“Looking back, hindsight is 20-20. At halftime of that ball game, I think it speaks to the belief of our team and the toughness of Luke,
and yet sometimes you’ve got to be honest,” McElwain said. “He was banged up, played that way and, you know, looking myself in the
mirror we should have made a change at halftime. And yet, part of the reason that we didn’t, obviously didn’t know the severity of it, No. 1, and No. 2, there wasn’t ever a panic. He didn’t play up to par and you understand why.”
