Hmm. Before you start lolling, you might just want to take a look at that goal again.
That OG was actually the result of an error on the other side of the pitch. High ball up the line, which our right-back/wing-back misjudges, gets caught under and flicks on. The whole defence is now turned and running back towards goal, full pace, whilst their left mid has time to run on unchallenged and then drill one across the six yard box. Haynes is actually in a pretty decent position at this point; the correct side of the attacker with relation to the cross, and touch tight - but because he's running back full tilt it's going to be hard to do anything except push it towards goal. I'd still rather he tried, because at least he's trying to disrupt, whilst the attacker on his shoulder is trying to score.
Most people who've played and/or watched the game know how dangerous that ball is, and how difficult it is to defend. That's why you try not to get caught having to defend them. Far better defenders than Haynes would have done the same thing, or worse, been on their heels and five yards behind the attacker watching him knock it in. If you're pulling his performance apart based on that OG then politely, I don't think you've got your analysis quite right.
