Not the 12th best left tackle, the 12th best tackle. He was the 7th best pass blocking left tackle in the league, something extremely valuable to us. By the way, PFF doesn't take into account the chemistry of the offensive line. When you have to come to a new team and play with a backup left guard, you won't do well. Offensive lines thrive under chemistry and continuity, something Monroe didn't experience. Look at the Pro-Bowl. The best offensive lineman in the league (for the most part) and how well did those offensive lines do? Not very because they lacked chemistry. I believe he's an elite left tackle. If we go by PFF, he's always a top 10 left tackle, aside from his rookie year. He was number three in 2011, number 10 last year, and number 10 this year. Once he gets a full offseason with the Ravens and a competent left guard, he'll be golden.
