Ulster coach Matt Williams acknowledged his side's failings after their 16-14 Magners League defeat by the Dragons on Friday.
Williams watched his side squander several glorious try-scoring chances against the Welsh outfit.
"That's two game sin a row we outscored the opposition two tries to one but manufactured a way to lose,” he said.
"You can't keep dropping the ball in the opposition half and expect to get tries.
"There were four tries (we squandered) and we should be sitting here talking about a bonus-point victory.
"Our defence was very good and we threw the ball around and we were entertaining."
