Sometimes this is true. But that's only when discussing bad to good QBs. When discussing great QBs, their stats don't dip with increased volume of throws.
I guess you could take a look at Wilson's college stats. You'll notice a pretty significant difference between his stats at NC State and Wisconsin. It's the same sort of deal. The difference between just his junior and senior year is 40 attempts vs 22 attempts per game. His rating, completion %, and yards per attempt made a huge leap.
