Agreed somewhat, but the scenario you present is ideal and rare, namely, "perfect route combined with perfect pump fake." And no it will not beat the corner every time. Several variables must be taken into account. You think a CB is going to bite on a pump fake on 3rd and 15 every time? Pump fakes are generally used on double move routes or when the play has a route combination to get a 2 Deep Safety to Bite on one of the routes. No CB is going to bite on an out and up, curl and go, corner post, post corner on 3rd and 15. And they might not bite on it if you have not been previously taking the curl route.
But definitely, the WR/DB interaction, the WR route running, the DB press tech, trail man tech, hip riding all need MAJOR work. After playing online for a couple of days, this entire game needs some MAJOR WORK
