I don't think he was ever supposed to start season 1 behind one of the worst O-lines and WR groups I have ever seen. He was forced YR1 and it was like being in Wyoming still as a rookie QB in the NFL. He did learn some stuff and flashed some amazing skills YR1 though. YR2 with a competent O-line and better WRs, you could clearly see the progression. YR3 I knew he'd be better, just not this much locked in so fast and reading D's the way he is. It's truly impressive!
It's scary to think what YR4+ can bring. Has Allen even hit his ceiling yet? This is an absolute thing of beauty that I (and 99% of yall) have been waiting for 20+ years now. Even if Josh is at his ceiling now and continues to play at this level we are winning a SB and soon.
