We have release 1 sixth round pick in the last 8 years, and he signed to the practice squad (Markell Carter).
Wendell was the worst rated center in the NFL, he allowed 37 QB disruptions, and Connolly was third to last amongst guards and allowed 33 QB disruptions. They were the starters but they did not play well, and right now it is an open competition in my opinion.
The most effective depth chart in my opinion would be –
LT – Solder
LG – Mankins, Kline
OC – Connolly, Stork
RG – Cannon, Halapio
RT – Vollmer, Fleming
With the hope that Stork could take over sooner rather than later for Connolly at center.
