I listened to all three Locke pod casts. I don't know if it is the individuals or the extra 2 years of school but RJ Hunter was a much better interview.
Portis seems simple, but it might be my impression of him saying cliches in a Karl Malone accent. I like his can do attitude.
I think some players just have some more rehearsed answers. Portis said in an interview that he usually gets nervous when doing interviews and he started opening up more this past year.
