Who cares what he thinks? He’s famous for mastering the art of spiral throwing a ball, which is a skill perfected by cavemen using spears to hunt with. He is no smarter or more educated than those cavemen were. In fact way less so due to the brain damage.
He actually is very intelligent, as are most NFL quarterbacks. He supposedly scored a 1310 on the SAT, and got a 35 on the NFL's Wonderlic test (well above average). Also QBs don't suffer nearly as much brain damage as most NFL positions, especially Rogers.
