I have no stats to back me up, but I feel like Bakh has had a very solid second half of the year. He hasn't struggled with speed like he did early on, nor with power like he did last year. Going into this year I wasn't sure he could be the long term solution at LT but now I'm beginning to think otherwise.
Here's an interesting question, how would you rate the OL from best to worst? I'd put Sitton first but after that I think they are all pretty similar
Sitton
Lang
Linsley
Bakh
Bulaga
