The Oakland Raiders' offensive line has been an impenetrable force this preseason.

Through two preseason exhibitions, the unit has not allowed a single sack or quarterback hit and has earned an 89.3 pass-blocking efficiency rating from Pro Football Focus (PFF).

This is good news for starting quarterback Derek Carr, but it also speaks to Oakland's impressive depth along the offensive line. Backups such as Austin Howard and Jon Feliciano could be starters for most other teams across the league.

While Carr should have plenty of time to throw, the Raiders still have plenty of room to improve when it comes to run blocking. They are not as imposing on the ground, although the addition of a mauler in left guard Kelechi Osemele has made the O-line a bit more effective in this department.

Overall, the offensive line figures to be one of Oakland's most dominant positional units this season.
