Some limemen can play multiple positions. Evans is not one of them.
He played well enough as an inexperienced right tackle, but was a liability on the other side of the line and moved inside. He is not a left guard. I felt sorry for him, for the shame he must have felt, when he turned to pick up Stafford after totally whiffing a block.
He simple wasn't ready. He took a lot of flack and if he complained we never heard it. He may do well as a reserve and someday starter at his natural position at right tackle. I wish him well.
