23. Patrick Kane
Kane demonstrated his immaturity in 2009 when he punched a taxi driver. The reason he punched him was incredibly stupid. The taxi driver assumed that Kane and his friend left him a tip and didn’t return the change. However, this upset Kane and he attacked the cabbie. It was a dumb move and one that landed him in court. Obviously, it wasn’t good for his reputation either.
This is the sort of situation that young athletes find themselves in too often. They don’t drink often because that would inhibit their performances. But as a result, they have no tolerance. Combine this with their competitive arrogance and it’s easy for them to make idiotic decisions. This one came back to haunt Kane because the case was high-profile. Kane ultimately apologized to the driver.
