This has been in the works for a while. Smith was gone from 2014-2016. He was a quality control coach at Texas A&M. He is a great o-line coach. It’s a pretty big loss, but Carthage won a title without him. I think everybody is really happy for him. That is a great job, and another step towards being a big time HC one day. He will do well.
One person not mentioned enough is Darren Preston. Carthage DC. He will surely leave for a HC job one day too. Now that one will really sting IMO.
