Yes, There most certainly is a reasonable argument against that. There are two examples of people being labeled a thug even though they are not violent street criminals. You are saying that it is racist to call one that but not the other because he had a physical style of play. Does that honestly make any sense to you or are you just grasping at straws? So is it acceptable now to call anyone with a physical style of play a thug?
There is a difference between labeling someone's extremely physical play as "thuggish"... because that makes sense... and labeling someone thuggish for being cocky which doesn't. I'm sad you can't see the difference. Read the definition with a clear mind and you will be able to understand the difference.
