Yeah I really don't think Pete thought Geno would be a top 5 QB and find that almost impossible to believe. I think Pete thought Geno could very well be good and run the offense in a year where he knew they were probably rebuilding. Pete always does Pete talk but if they truly thought Geno was this good then trading away Russ wouldn't have been so hard as reports are he was dead against it until the very end and finally caved.
Pete probably had more faith in Geno than I did or most fans but he didn't see this coming and that he was always as good as Allen, Mahomes, Prime Russ etc.
I'd also add its still very early. Geno could fall off a cliff here soon and it shouldn't shock anyone. I really hope he continues his play and I'm becoming a believer more and more each week. It will be interesting to see what happens when teams adjust to him and how he reacts to that.
