Everyone bitches that we don't have any veteran leaders on this team and then when a player comes out and says playing with younger players is generally a liability everyone calls bullshit. Make up your minds.
Besides, when does a player become a veteran. 2 years, 3 years, more. Does it matter if he is a full time starter or a spot duty player?
The more you play the more experience you get and if you have great skills to go along with that experience you could be one of the great ones. If you have skills but not the brains to take advantage of the experience you may not go far. If you have all the experience in the world but your skills are limited you may not go far. You may stick around for a long time and be a decent role player but you probably won't excel.
Great skills can make up for lack of experience in the short term and vice versa but long term, the really good ones need both. Young guys, even those with great skills, don't have the experience and in most cases it will show up eventually in the form of a mistake. I think that is what Williams is saying. Obviously that does not mean the experienced ones don't make mistakes. Everyone does.
I also love it when people pick one guy and use him as an example as to why a premise is wrong. "My uncle smoked 3 packs a day and lived to be 100 years old. You can't tell me smoking is bad for you." Its the same way with football players. One young rookie has a decent year and all of a sudden the idea that younger players may not be as good, or maybe we should say consistent, as older players is hogwash.
