I disagree with this in the context of the goal.
If a LB sees a runner, coming through the middle, with no one else around he absolutely has to track him, tuck in to cover the run etc.
As a defender you have to try and cover the immediate danger, McGinn in this case, there was no other danger/attacking players around.
I' not blaming Danny for going down, he was trying to block a shot and got it wrong, it's his starting position that was at fault. There was no need whatsoever to be that wide.
I'll just have to agree to disagree
