Issue with cover 2? So if you can read a D you will know when it is zone or cover 2. You also will study more film and figure out ways it is disguised, ways to attack it. Meaning that you improve. That is the point and only point most are trying to make. Is he isn't getting any better at it. Numbers say a lot more than a person explaining. So... numbers are below. I took this from an article that came up when you put in "Watson reading defense issue" it says he is good against zone. Which is good.

This season, teams are playing more zone coverage against Watson and the Texans offense, which makes sense since they can keep an eye on the QB and keep the receivers in front of them.
However, Watson is shredding zone coverage averaging over nine yards per pass attempt while completing 70 percent of his passes. Against man, Watson’s numbers are pedestrian.
In particular, the Houston quarterback, in a limited sample size, has struggled to figure out cover-2 man coverage or two-man as it’s often called in football.
