I'm feeling a little better about it. The only factor nagging at my confidence was the offense anyway, so a speedy receiver with reliable hands is just what the doctor ordered.
The Saints are going to put up points, especially with KJ out I expect Graham to get 5-7 catches to keep drives alive. If we're going to win, we're going to need to score (as opposed to a defensive, 10-7 battle or something), and we can't rely on fumble returns or Wilson banking TDs off people's faces again. Whether it's great kick returns, long bombs, or just better third-down efficiency, Percy should be a net gain somewhere on the field.
