General Lee was considered a great General. But does the battle of Gettysburg prove that wrong?

Lee was a good general at best. He got lucky with our first commanders who played chicken **** games and only faced the confederates with even or underwhelming numbers. Grant actually knew what he was doing, everytime he expected a battle, he would send for replacements before it began. Attrition is the name of the game folks. Lee was good, but not great.
