Assuming the worse, all is not lost. many teams have started the season with a day #3 rookie on the O-line. Last season rookie 6th round pick Trey Smith started all 17 games for the Chiefs. Chicago also had a 5th round pick on the O-line play all 17 games. Perhaps we discover something really good about Asim Richards and a negative turns out to be a real positive.
Edoga does have some game experience, he has started 13 games during his four years in the league.
I agree, it not optimum by any means, but it's not like they are only going to roll out 9 players on offense.
