When Jags fired Jim Turner shortly into his tenure as Head Coach, BC kept it in the family by replacing Turner with Jack Bicknell Jr. Bick was the opposite of Turner in many ways and quickly won over the OLine. Bicknell will have to use some of those same people and coaching skills again as he is replacing Turner as an Offensive Line Coach with the Miami Dolphins.
Bick won't be doing it alone. He's technically the assistant OLine coach, but I assume he will do his part of changing the culture.
I don't know why Bicknell has bounced around the NFL since leaving BC, but based on the success he had replacing (and repairing a unit) after Turner once, I assume he can do it again.
