The hosts scored twice within the first half-an-hour, and despite going down to ten men, were able to comfortably see out a first win of the season.
Sharing his disappointment with what he saw during the 90 minutes, Jones said: “That was pretty much unacceptable first half. For the things that we do and how we go about our work, that was unacceptable. The way we defended, the way we wanted to take shortcuts and not do the basics well cost us the game.
“I will take responsibility, I felt I picked the wrong team but it is inexcusable anyway because after five minutes you couldn’t tell that. We just didn’t do the basics right and we’ve done the basics right so many times but that was as poor as performance as we’ve had for a very long time, especially since I came back. Maybe Birmingham at home but we were second best all over and that’s something that doesn’t happen to us very often.
“We have a lot of injuries and we have people that need bedding in and to learn what we do but we just didn’t defend well enough, we weren’t aggressive enough, we didn’t do the basics and for me, I thought we were really, really poor.
“They had more energy than us, they won 50/50s, everything about it wasn’t what we normally do and that is the worrying thing. Second half we improved but I don’t think we could have got any worse to be honest with you.”
