He's been a mixed bag. To be sure, though, that RT position isn't as easy to play as people think it is.
I'm wondering if there's maybe an issue with Frederick here early. Either health, or that he's not entirely comfortable with Green next to him or something. It seems like we're getting physically beat to combo blocks in the interior for some reason, and I'm not sure why. I can't remember getting this much penetration between the OGs other than with the Giants and MIN games last season.
And then the TEs (both Hanna and Witten) seem to be struggling to get to their edge blocks. The whole offensive protection just looks off for some reason, and we're getting beat in the backfield too often as a result.
