It’s the same in every level of football. Your best players can only shine with a great offensive line in front of them. When things are going well you never notice the offensive line, but when things are going wrong you often can not look past them. Football as a game honors skilled positions, but those positions would get no where without the help of the offensive line.
The Chicago Bears offensive line protects Mitch Trubisky. Trubisky passed for 3,223 yards last year, that would not have happened if it was not for the O-Line. Tarik Cohen rushed for 444 yards last year, and scored 3 touchdowns, that too would not have happened if it was not for the offensive line.
