T.J. Lang is a really good guard. The Seahawks could have signed him prior to the 2017 season and made him a long-term starter. Before we get too excited about signing a better player than J.R. Sweezy and D.J. Fluker are, one has to remember Lang has missed a bunch of games the last two years.
Still, Lang is a two-time Pro Bowl player and is still just 31 years old. He was released by the Detroit Lions on Friday. Offensive linemen can play good football well into their 30s. And guards have to have a little less athletic ability than do tackles.
