It's about his decision making as a whole. More often than not he tries to shoot through players.
Look at the other 5/6 examples to get a bigger picture.
In that one he could have laid it square, that's the way opponents have scored past us by just laying it off in that position to a free man and tapping it in. It isn't as obvious as some of the others but again that was about the 4th time in that game he made the wrong choice, hence players are pissed off with him.
At his 2nd touch he takes it on his right foot, even here you can see McNulty screaming for it.

It's all well and good a striker being hungry to shoot and get goals, but there is only so much before it starts to have a negative impact. Especially when you are chasing games, at 2 or 3-0 up it's not so bad.
