Rewatched the game in slo-mo, focusing only on the line, from left to right:
Humphries - decent game, a couple of mistakes, gotten between by the swim move a couple of times. Needs a better punch instead of lunging so much - that appears to be his biggest weakness.
Iupati - good game overall, combined with Humphries, they moved the left side a few yards deep on a few run plays
Shipley - probably the worst player this game - didn't make too many mistakes, but physically gets beat the most and has the least to contribute. On a few run plays, everyone but Shipley is pushing past the line of scrimmage. Asked to block downfield a few times and is terrible at it, reminded me of a comment by K9 referring to Cooper getting to the second level and then not blocking...that was Shipley this game
Wetzel - wow, what a mixed bag - has a decent punch and passed off defenders much better this week, not so good at one on one blocking very long, not a natural guard as the shorter, fatter DTs get underneath him/around him too often
John - decent game, needs more strength, but made some good run blocks, did ok with the edge rush by driving them wide, didn't handle the transition to inside moves by the defender so well, better than last week though - looked like an NFL backup at least. Very good second level blocker, athletic and actually blocked someone
