I posted a comment the other day that I have a friend who visits with Harrell on a regular basis and said that he was not going to coach anywhere. So after the news came out, I went to tell her that she was wrong. Well, she said that they saw him this weekend and I learned there is more to this story.
Per thier visit, Harrell is NOT going to be coaching at OSU or on the payroll. Since Holgerson will be implementing the same offense at OSU, he asked Harrell to help him out with teaching the system to the OSU QBs. With it being the off-season and Graham "not having anything to do" he accepted the offer to go help out for a little while while Holgerson gets everything in place. So, it appears that ther is more to the story and Harrell is just helping out a friend.
I hope this eases some tension.
