Don Barclay is the epitome of a journeyman depth signing along the offensive line. He began his career as an undrafted free agent with the Green Bay Packers and earned a spot as a reserve tackle on their roster for six years.
During his stint with the Packers, he mostly played right tackle, and aside from stepping into a starting role for the 2013 season due to a swath of injuries along the O-line, he has stayed in a reserve role.
At the beginning of 2017 after his rookie deal expired, he was brought back for a small one year deal with Green Bay in the off-season, but was let go with an injury settlement after being placed on injured reserve, then bounced around from the Lions and Saints, before being signed to a futures contract by Denver, after sitting out the 2018 season.
