RG3 and Foles were in gimmick offenses that the league wasn't prepared for. The big issue with RG3 was his basic fundamentals were a catastrophe and the offense was fooling LB's to bite on the play fake and it would leave receivers wide open over the middle. He couldn't throw outside the numbers with any efficiency and struggled to see over his linemen and therefore needed the ballfake to suck the LB's in and give him wide open passing lanes. The league figured it out and he ended up being the RG3 we know and love.
Very similar for Foles as the league wasn't prepared for the Eagles offense outside of Monte Kiffin, which Foles had his worst game that season against.
I would compare Dak's season more to Roethlisberger's in 2004. At the time guard Alan Faneca told reporters he wasn't enthused about having a rookie starting, but with Tommy Maddox going down there was nothing the Steelers could do. Ben was far from perfect and was more of a 1-read QB, but his ability to allude pressure and throw on the run made him tough to beat and the Steelers went 15-1 that season and then won the Super Bowl the next season.
Dak has much better pocket skills at this point than any of the QB's mentioned at the same point of their career. He's also extremely accurate and his 2 best receiving threats are Beasley and Witten. So, it's no wonder he's not throwing a ton of long balls because that's not Beasley and Witten's game.
Meanwhile, Roethlisberger had Plaxico Burress, Hines Ward and Randle El for is receivers.
What Dak's strengths are his ability to locate the ball and beat defenses out of the pocket and beat teams by bootlegging in either direction. Combine that with our outside zone runs that makes it very hard for defenses to beat. And when you prepare to defend for that...they can go shotgun with a RPO.
Certainly, there will be more of a book on Dak as time goes along, but I would expect that to consist more of finding a way to take Dak's weapons away from him than actually being able to stop Dak himself. And that's what separates Dak from the Foles' and RG3's.
