I don't understand how/why some people have such strong feelings about a 2012 recruit that you've never seen play. Going strictly off of what ESPN writes about a kid is a very dangerous road to go down, as some above have pointed out. Iowa State/Hoiberg are obviously very serious about this young man. At this point in the program, why not trust the staff?
And as for the Railey comparisons, I feel like they are way off. I've never seen Niang play but he is 6-foot-7, 225-pounds. Very different games.
Best thing about Niang is how well-spoken & respectful he is. He was great to interview. Iowa State needs high-class 4-year players like this to mix in with the current transfers. That's why guys like Ejim, Odunsi, Okoro, Niang, Sledge, etc. will be so valuable going forward.
