The Mahomes lust is hilarious. Even being coached by the great Andy Reid, Mahomes admitted he didn't really start reading defenses until his 3rd year. Would he get overwhelmed by BOB and his version of the EP offense that requires so much pre snap reads and line calls? Being a gunslinger, would the mediocre Texans OL force him into turnovers that BOB would find unacceptable? There are so many variables, but your QB opinion is based on a single evaluation that ignores all variables including coaching, complementary skill positions and the OL.
During Mahomes first training camp, he struggled and was turnover prone. Would he develop at the same rate under BOB? With BOB's quick finger to pull QBs and not even wanting to move up to get Mahomes, if Mahomes is struggling, would he bench him to show up Ricky? Give Mahomes and the Chiefs credit for quickly recognizing his struggles and working with him, implementing Air Raid concepts and plays into their playbook. Give Mahomes credit for really working with the Chiefs staff and improving his game. To say the same would happen with the Texans is a useless exercise based on hindsight.
After practicing with Mahomes on a daily basis, here is Tyrek Hill on his initial opinion of Mahomes. So, you knew more than Hill who saw Mahomes in practice. Even after the first year, they didn't know what they had in Mahomes, but you did? Hindsight is an awesome thing.
