As Vito explains
UNT lost two starters to graduation in center Sam Rice and tackle Trey Keenan. The Mean Green also lost Wylie Reinhardt to a career-ending neck condition in the offseason.
This offensive line was a sore spot. Too many sacks, leading to too many turnovers, leading to too many lost-cause drives. The signing class had some talent — and maybe some that could contribute right away — but signing guys with experience is a good thing. The staff likely does not want to make a habit of signing former FCS lineman to fill the depth chart, but this is a good thing considering all the signings. Depth was a big problem last year and these kinds of moves go a long way toward addressing that issue.
Seth told this blog he had a ‘few’ things lined up. Vito reports a source said more were coming. I think we know what to expect this summer and early fall.
