The Detroit Lions' coaching changes are continuing to leak out, with the latest news being that the team has severed ties with offensive line coach George Yarno, according to Anwar Richardson. This move comes after word leaked out earlier that the Lions aren't planning to retain wide receivers coach Shawn Jefferson and running backs coach Sam Gash.
Just as with Jefferson and Gash, it does not appear that Yarno was fired. Instead, based on the wording, it seems that Yarno's contract was up and the Lions simply informed him that he isn't being offered a new contract.
Yarno originally joined the Lions in 2009 when Jim Schwartz took over. The Lions' offensive line has been a hot topic pretty much every year since then for their problems in the run game. From a quarterback protection standpoint, the offensive line has generally done a pretty good job considering just how much the Lions pass.
Regardless, it's clear the Lions are indeed planning to make changes for 2013. Just how wide-scale these changes will be is still unknown, but so far three offensive assistants are out.
