Here's the link to another article that says a lot:
Here are some quotes that I found interesting:
“The one thing that Heacock did really well was, everyone bought in,” Radakovich said. “Everyone loved him as a coach. Wolford was a much more polarizing figure. You either loved him or you hated him. I think that was an asset at times but it was also a detriment, because when things went bad a lot of guys weren’t ready to stick by him.”
“Guys would say, ‘What superstar is going to come in now and fizzle out?’” Radakovich said. “That lack of continuity makes it hard to build that bond you usually see in a football team, where you’re fighting for your brother. We always had great talent but with that comes a lot of individuality.”
"Shaw, who went through four position changes in his first two seasons before developing into an all-conference tight end, said the coaching staff also played favorites, which hurt team chemistry.“We knew it as players and it would rip through the locker room,” he said. “I’m not afraid to admit that. They were bringing in different guys that maybe necessarily shouldn’t have played right away, so there was never that true team camaraderie. “A lot of us really did buy in, like [RB Jamaine] Cook, [QB] Kurt Hess, [OL] Lamar Mady, but you know that was their personality. Wolford had a personal relationship with some players, but it was lacking with other players. I think he was a great emotional leader but he couldn’t always relate on a personal level.”
"Both Shaw and Radakovich said Wolford is an extremely talented offensive line coach but felt he struggled to develop a complete team, particularly the defense and special teams. Shaw also felt the coaching staff struggled to make second half adjustments, often dominating the first half offensively before getting out-schemed in the second half."
“I love Wolford and I don’t regret the decision to come there,” Shaw said. “He’s a great recruiter, so it was never a problem trying to get talent. But I felt like we should have been a playoff team a couple times and made a couple long runs.”
Very telling statements about Wolford's coaching style.
