That first season, Bakh had a lot of trouble on the job. A lot of fans wanted him out of there, saying he couldn't pick up the outside rush, and was not good enough to play there. You may not remember, but I do, when people screamed for his head. I saw his potential, and realized he had a decent future.
Where you got the impression he played well beats me. He showed promise, and improved as the season went along, but he was a victim of being a rookie. Most fans did not see that, they just saw that he wasn't good enough in their minds, to protect Rodgers' blind side. It was going to come, where he was that good, but even prior his second season, people were clamoring for the Packers to draft someone who could play left tackle.
Here's some stats from an old report I dug up on the internet about his first year in the league. He was not that good statistically, and that is exactly what fans saw.
