First it was the shoulder stretch tic that people noticed vs Oho State, which he’s always done with evidence to back it up: Then it’s the wincing/facial expression proof from the past which you mentioned.
Arch has played full expected starter minutes for 2 games without missing a snap. He has thrown lasers all over the field, some god awful and some good, with healthy velocity. He has run the ball plenty in both games. He and Sark have vocally shot down the rumors.
What would be the benefit to Arch personally hiding an injury? What would make that beneficial to his present and future as a college and pro QB with the ridiculous spotlight and scrutiny on everything he does? He’s playing hurt with the blessing of Cooper, Archie, and the rest of his family? And they want him to suffer through the pain against San Jose State? And to be mocked my social media and analysts nationally? That’s part of the plan? “Don’t get better Arch, deal with the pain and all the unfair bullshit that comes with it. This is what we want for you.”
