Edinburgh “should have lost” and their defence was “horrible” in their 31-30 win over Benetton on Friday, says head coach Richard Cockerill.
Benetton outscored their hosts in tries but missed four conversions at Murrayfield, with Simon Hickey more accurate with the boot for Edinburgh.
“If they convert the last try, they win. Its as simple as that,” Cockerill told BBC Radio Scotland.
It was Edinburghs second Pro14 win of the season and they registered their third bonus point from five games to draw level on 11 points overall with Benetton in Conference B.
Cockerill said his side were more than happy to secure five points but that some of their play without the ball left plenty to be desired.
“Ive just spoken to the guys in the changing room. Were not going to accept that level of commitment defensively. Its not good enough,” he said.
“We did enough to make that a decent victory. Its a good win but its a pretty poor performance in the end. Its not like us. Its not something that I want to repeat.”
The Blues denied their South African opponents a maiden win of their new season while Edinburghs result means that they move off the bottom of Conference B.
