Kline was a UDFA for the New England Patriots. In classic Patriots fashion, they groomed him into a started during his second and third years. Kline moved to the Tennessee Titans in 2016, where he started at right guard from 2016-2018. Those three seasons were clearly his peak.
The Titans decided to let Kline walk after 2018, and he signed with the Minnesota Vikings. Kline saw a bit of a step back in play from his reputation with the Vikings but still held up well. He started at right guard for 13 games and their playoff run.
Kline is 30 years old but has fewer health questions than the other names mentioned on this list. He has experience at right guard and right tackle, and his peaks are that of a solid, or above-average starter.
On a cheap contract with a one-year, he could step in and prove as a reliable starting guard. He, at least, would provide great competition for the position. If the price is right, the Chicago Bears should be interested in Josh Kline.
