No it's not, but it's a problem that is allowed to fester. Do you want young guys on your team watching him as an example? I don't think so. It's the same thing with Prior, I wouldn't want my young pitchers seeing him complaining of discomfort every time the wind blows, set's a very bad example. If these players don't have the self pride to put forth the effort, it's up to the manager to instill it. If that doesn't work, you get rid of them, unless it is ok to have these types of players setting the tone.
