I mean dude you can't bring up breaking bears rookie qb records as a flex. His rating and QBR were bad, his advanced stats were bad. He took an ungodly amount of sacks because he couldn't process defenses quick enough. If you look at it objectively its easy to see why people are concerned. What did he show that resembled a generational talent, honestly? Getting outplayed by 2 QBs drafted after you doesn't help at all either.
Im in full agreeance with mul21. It's a complex system and it could be rough for a few weeks. He has that excuse built-in if it is indeed the case. He will get a pass to an extent. But there are a lot of flaws in his game that will be under major scrutiny.
