I do appreciate you posting the info, but I'm not sure it's cool for a doctor to be commenting on Mayfield's ability to play without having examined him or seeing his scans and X-rays.
It's just a guy trying to build a business.
He was the Chargers team doctor for 17 years. Yes, he's building a new business. He's been incredibly accurate in his video analysis, diagnosis and time table for return for players.
Dave... he specifically states he has not personally evaluated Mayfield. He's simply offering his professional opinion.
He's good for gamblers, too!
