Like most people I watched the game and thought Gibson was godawful. I saw him get bullrushed into Vaughn. I watched him use poor footwork and fall down. I watched the 3 holding calls.
The thing is I rewatched the game and started doing my routine of watching each play 2 or 3 times to see how the lines and skill position guys were doing. Thing that stood out to me was the Gibson started out at RT and for the first few series I thought he played well. He was getting to guys on the second level. Beating the rush to the edge and driving the LDE in the run game. Then he switched to LT.
That is when the wheels fell off and well we all saw it and it wasn't pretty. First thing that I noticed from the beginning this offseason is that he is awkward in his stance and not comfortable with his footwork. That is still very much the case from the left side. OTOH, on the right side he now looks comfortable in his kickslide and such.
This may be somewhat controversial but I would like for them to keep him and continue to develop him. He needs to improve his flexibility still but his strength and agility is remarkable when he is technically sound. Further, I feel like despite his struggles on the left side that he has made considerable progress on the right side.
