I am betting that Kirk stays around a few more years (he deserves to retire when he wants to), but Brian moves on either during season or just after. He is a good O Line coach and there were hopes that he could be a good O Coordinator, but it just did not work out.
While we are throwing stones in the glass house, anybody care to fathom how many head coaches and assistant coaches have been through Lincoln in the last 20 years? Stability and good choices in coaching have not exactly been the norm in Lincoln.
