Not really... go re-read the article. His ranking and % is already adjusted for the dropped passes. He's at 35% if you count the dropped passes and at 40% if you count the drops as completions. The 18th ranking is at 40%, not 35%.
You can just use your eyes and see an inconsistency on deep balls, you don't need any stats. My hope is that is just the speed of the WR that he's not used to or something else that can be fixed through reps... however, even if it isn't easily fixed, he's still has so many upsides... I wouldn't trade him for someone else

If you had to pick one area to be deficient in, I'd go with the deep pass.
