理论上，&西北航道&的完全开放可以让欧洲到亚洲之间的旅程缩短2500英里。

I just hope his defense doesn't make me throw stuff at my TV.He should be at least a decent scorer and maybe a reasonably good rebounder,but watching him at Gonzaga he was a terrible defender and it didn't seem to bother him at all.I don't think we're going to be able to hide him in the corner of a 2-3 zone the way that the Zags did,but we're probably going to be forced into playing a lot of zone because of him unless he makes a committment to his defense.

我只是希望他的防守不要让我关掉电视，他至少是一个相当不错的射手，并且有理由相信他是一个好的蓝板手，但是看他在大学的比赛，他是一个不敢恭维的防守者，而且那似乎完全没有影响他，我想我们不能像Zags那样在把他隐藏在区域防守之后，我们或许可以分成区域防守因为他已经承诺他的防守。
