The hang up is the offensive play-calling duties. Oklahoma State has a coordinator and play caller. Henson, who make a reported $510,000 at Missouri, would not want to give those up, and it is virtually impossible to coach the entire offensive line and also be the play-caller. That is a lot of time-consuming activity.
Doug Meacham, currently at TCU as co-offensive coordinator and wide receivers coach, has not coached the offensive line in awhile. He has spent much more time with receivers lately. I think that keeps him from being considered.
Some serious candidates, in my opinion are the following:
Herb Hand is most recently the offensive line coach at Vanderbilt. But he showed his prowess in Oklahoma before and coached the offensive line for Steve Kragthorpe at Tulsa, and did a tremendous job for the Golden Hurricane. Hand has also coached at West Virginia and is proven to be a good recruiter and has done a good job at Vanderbilt. The question is whether he will follow James Franklin to Penn State? Hand is a really good coach.
If looking inside the Big 12, Kansas State has had and continues to have one of the best offensive lines in the league with Charlie Dickey handling the offensive line since coming from Utah when Bill Snyder took the reins back over. Dickey was instrumental in the success at Utah including his final season there when the Utes went 13-0 and beat Alabama in the Sugar Bowl.
Ronnie Vinklarek has been at Oklahoma State before and he has done a tremendous job at Rice coaching the offensive line for the Owls. Famous for the story of how he raised his brother after the death of his parents, Vinklarek is a good old-fashioned offensive line coach.
Wickline's first graduate assistant at Oklahoma State is Glen Elarbee, who has risen up the coaching ladder. His rapid ascent includes going from being a graduate assistant for Wickline to coaching offensive line and being offensive coordinator at West Georgia to his alma mater Middle Tennessee State as offensive line coach to Houston in the same capacity. He was just hired after Christmas to join Blake Anderson on his new staff at Arkansas State. He is still young but has had a lot of success in a short period of time.
