He's totally right.
They make it so easy on these college QB's nowadays that they are entering the league underprepared by QB standards of 25 years ago. They dont have snap counts. They get up to the line and stand there for 25 seconds while their coach reads the defense and then signals in a play. The RPO is becoming a staple of offenses and its obviously not a complicated play to execute. And he's right, there's really no ball handling aspect to it so that's becoming more rare and a lost art.
Now you have these college kids who can barely wipe their own ass in football terms entering the NFL and you have Head Coaches and GM's so desperate and pressured to win quickly because its a microwave society and so much money is involved, plus their own employment is on the line. So what do they do?....they adapt their playbooks and run more college style schemes and RPO calls in order to get the most out of the young QB's as fast as possible and shorten the learning curve. There is no more waiting and developing QB's and being patient while they take their lumps for the first 3, 4, 5 years. You almost have to draft one before you even need one so that you can let him sit on the bench for half of his rookie contract and learn while you have a competent starter and are winning enough to keep your job and actually have some time to develop and mold a QB in your system/organization. Tons of offenses have answers to defensive looks built in so its almost like QB's just have to memorize the Offense rather than truly learning it and eventually being able to command the offense on their own like Peyton, Brees, Brady, Rivers, Eli, Ben, etc....
