Unlike McKinnie, you don't have to question Oher's physical condition or desire. He looks like a tackle in a tight end's body and he practices as hard as he plays.
The major adjustment are the actual steps while firing off the balls. It doesn't sound like much, but it's a hard adjustment because we do everything by memory. If you step incorrectly, it can cost you a second and a second in the NFL can get you beat or change the outcome of the game. That's why it was good for Oher to get so many reps on the left side during minicamp.While filling in for McKinnie during several minicamps in the offseason, Oher played well on the left side. He played with confidence and had no hesitation about his blocking assignments. He only jumped offsides one time. But that doesn't mean he'll play well during the 2012 regular season.
There are so many questions about this offensive line. When the Ravens drafted Oher several years ago, you thought he would be an answer at left tackle. At this point, he just seems to be a reasonable solution to a problem area instead of a definite answer.
