A section of supporters called for Davey to be sacked during another nail-biting run-in that saw Barnsley narrowly avoid relegation for the third successive season, but Cryne insists the Welshman has done a decent job under the circumstances.
Cryne said: "I understand the constraints which Simon has to work under. I believe he's a very good young manager who is working within our limitations.
"Unfortunately we are one of the smaller clubs in the division in terms of gates and we're not as fashionable as some of the big city clubs. It's always going to be a challenge to be successful in the Championship.
"I think when he picked up the mantle from Andy Ritchie, he caught some of the backlash from our bad form. I think he caught it unfairly. But since he's come in, we've become more professional as a club in many different areas. I understand his difficulties, but I have a lot of respect for his talent.
"Fans tend to judge the here and now and you can sympathise with them when results are not going our way. But I'm a fan and I'm able to be a little more tolerant than most fans because I can see what Simon is trying to do with the club. Simon has done well to keep us up, but the fans expect more."
