Clearly, Manuel needs to improve on his deeper passes, as there’s a sharp decline in his completion percentage on passes twenty or more yards downfield (30.2 percent in 2013). 35 percent of the 43 deep attempts were on target, while another 30 percent were overthrown.

I don't think so.
And yes. Thad and Tuel both have a smaller sample size, and I have reason to believe they completed more passes per attempt over 20 yards than EJ.
