I agree with you that the NBA should come down much harder than they do on these incidents and that that would "also" go a long way towards having a better product on the floor.
Until I see that day, I will make my own line in the sand and do the job to protect myself and my teammates.
I guess I grew up in an era where confrontation is Ok, and actually very healthy. And there is a clear difference to me between physically assaulting someone in the form of a punch and giving someone a good bump or shove and then engaging in a heated conversation with them, letting them know what just happened is not ok.
I think we all experienced bullies growing up. I never got whacked and ran crying to my Mom and Dad to make the bad guy go away. If you didn't stand your ground, you would continue to get whacked, especially if the teachers weren't always there to monitor and/or punish the bully correctly.
When bad actions are taken - you address it head on, you don't wait for someone to hold your hand.
Can you imagine Michael Jordan getting hit like that - you don't think he would so far up into Kleiza's grill that Kleiza would think long and hard about doing another play like that?
To me that is the epitome of class and "just" toughness in sports.
Or should we say, "well, Kleiza was maybe having a bad day, we also need to think about his feelings and what he might have been going through..."
