Some reviews on here had me concerned about Waletzko's play against Jacksonville, but I went back and rewatched the first half only focusing on him and his game was pretty solid. He gave up a few late pressures until the last drive (our TD). Isaiah Stanback pointed him out on a sack that was given up by Farniok, but Waletzko did his job on the play. He gave up ground and then walled off, but he was struck in the back when Farniok was beaten by the DT off the snap (DT one-arm shoved Farniok out of his way) and then Ball lost contain on his man who polished off the sack.
On the last drive, Waletzko may have held on the deep throw to Tolbert that was called back by penalty. The broadcasters were saying it was offensive pass interference, but they never showed what the penalty was. Waletzko has a tendency, though, to put his arm around the throat of the defender when the defender is starting to get around him. He also did this on the TD throw to Tolbert and I thought it could be called holding. Other than those plays, there was only one pass rep where he clearly was beaten, and it was a quick throw so it didn't affect the pass.
Where I thought he had some trouble was his run blocking, especially early on. He tends to stay high in his run blocks so the defender works under him and loose. However, on the last drive, he seemed to keep his grip on the defender and made several solid run blocks. Of course, he was facing lower-caliber DEs by then.
I'm just not displeased, like I thought I would be based on some comments here. He has some things to clean up, but it as a solid first half for him overall. There was a play where Grier got hit because he and Ball didn't trade defenders on a stunt, but it seemed to be more Ball's fault because he wasn't in position to trade. If Waletzko had let his man go, the QB would have been creamed.
Just thought I would throw my two cents in after focusing on Waletzko for a half.
