One of the TV guys said that as the 2nd half started. No reason given, I assumed everyone thought the coaches took him out because he sucked.

Then, inexplicably to me, he's back on the field, AND sometimes not even with a helper on his side.

I can't explain that, and I think it was a game losing decision IIRC that last drive.

HOW could he be allowed to stay on the field? I am pretty much totally ignorant about OL schemes, but Stevie Wonder and Ray Charles' love child could have seen he needed to be OFF the field. He was laughably pathetic.
