Lot of similarities. The QB situation, not so much. Warner couldn't grip a football because his broken bones deteriorated his dexterity. Goff? What his excuse other than everything and the kitchen sink? Since '18, Goff has been a bottom tier QB. Warner had an injury riddled 7 game stretch. 41 games of ineptitude vs. 7 games of playing through injury. Just not the same.
Warner welcomed competition. His whole career was an uphill battle. If all it takes to alienate Goff is to say that everyone is under evaluation, then there's a real problem with him.
