As the starting quarterback of an NFL team, his handling of every single situation on and off the field has everything to do with being a leader. Everything he does reflects on how he is perceived and treated by his team, especially when it directly relates to team members.
The whole thing speaks to a total lack of maturity or integrity and directly undermines any lingering vestiges there may be of thoughts that he could lead this team. I jokingly said to IJR yesterday that we might as well cut him now, but I honestly wouldn't mind if we did. He has zero value to this team, IMO.
This thing by itself isn't a huge deal. Shoot, look at Ben Roethlisberger. He was assaulting women in bathrooms. That shows much more of a lack of maturity or integrity than not paying someone $600 promptly.
Geno has value to the team if Geno can play. If Geno can't play, then it's a moot point, but clearly there are enough people who think Geno still has a chance to succeed.
The problem is that there are a lot of little issues that speak to a bigger picture (airline issue, missing meetings, cursing a fan, etc). All of those can be excused by themselves, but when you add them all together, they are no longer isolated incidents.
