no doubt i listen to some rap music with very questionable lines (Rick Ross on UOENO is one that comes to mind instantly) but it doesn't detract from the product for me personally.
Big Boi and 3 stacks have a lot of leeway for me anyway because of how highly I regard Outkast.
Here are Necas highlights from World Juniors. Doesn't look like he excels in any particular area outside of skating but he works hard and doesn't make mistakes. I could see him projecting as a 3rd line center.
