Respectfully disagree, all players, including Qbs should Develop their body to their personal peak performance level, this is elementary in pro sports, especially a 22 year old who hasn’t nearly developed his body.
It’s Part of the job description, if you have any pride and intellect they will realize this, the ones who don’t will never reach their full potential.
Sometimes these qbs are like mlb pitchers who think if they develop any muscle it’s gonna affect their mechanics... it’s ridiculous and a BS excuse, let’s hope he’ not like this and doesn’t feel this way and reached his physical potential, after last year he needs to get some more musculature, stronger, quicker.
