The offensive line needs to be overhauled this offseason. OK, fine, I knew this one already, but it was reinforced every time Flacco got speared in the sternum or sandwiched between a pair of Bengals. Flacco was only sacked twice, but the Bengals hit him a bunch of times and their pass rush knocked the Ravens offense out of rhythm all game long. The Ravens also rushed for just 47 yards. As I wrote earlier, Monroe and Oher are both free agents, and there is no way both will be back (I suspect they will push to re-sign Monroe). Left guard Kelechi Osemele is coming off back surgery, which is risky business for a big lineman. And Gino Gradkowski didn't exactly take over the center spot. The only lock to start next year is Pro Bowl right guard Marshal Yanda. Earlier this year, I wrote about building offensive lines and the experts I spoke with said continuity and familiarity are very important. In this case, though, personnel turnover might actually be a good thing.
