You have to consider by "average game" he's surely referring to the big budget titles here. Clearly something like Toad, HW, the Zelda remakes, or Splatoon don't need to kill to perform well. But something like Galaxy or mainline Zelda, with years in the pipeline and large teams, have to sell that, and always do. The only recent one I think would have missed the mark is Xenoblade X. And possibly DKCTF depending on the budget for that one.
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
