For those old enough to remember, Robert Parish was the quiet, stoic one in the original Big 3. So much so that people wondered if he just wasn't a very nice guy. In fact, one of the reasons he ended up in Boston was because Golden State saw him as having "attitude problems."
"Just going by what I have heard, I have heard he has a talent for being difficult," Parish said. "But you can say that about most of us. I know I had my moments. For me, if I don’t know you, I come across as being aloof and distant if I don’t know you. I am just quiet if I don’t know you. I can be very stoic looking, that’s just my facial expression. I don’t smile a lot. I come across as being arrogant and dismissive, even if that is not the case. I know what it is to be misunderstood. I can’t say for sure that’s the case with Rondo, but I can understand it if it is."
We should only be so lucky as to have Rondo have the career that Robert Parish did. Though he's got a different demeanor, I've often compared Rondo's career arc with that of Paul Pierce's as well. Immaturity issues and trade rumors early on followed up with a lot of hard work and ultimately a long successful career. Again, hopefully Rondo can duplicate that success.
Rondo is a different kind of guy, but as you can see with Parish, there's plenty of room for guys like him to thrive in the NBA with the right drive and talent.
