Good initial work! I've been finding out the hard way how difficult it is to properly get a site up for the first time, especially the responsive menu system.
In terms of constructive criticism, it feels like the color scheme is a little off, and the content on the front page feels a little cramped (not sure if the two are related). Some of the mouse-over stuff may also be a little over the top and be distracting for people.
On the article pages, I would personally choose a different font and maybe increase the line and word spacing a little. I've been playing with the Google font 'open sans' and quite like it, although there's lots of other choices to pick from. The text column should probably be made a little narrower on the full screen desktop setting. I've seen some reports that suggest no more than 10 to 12 words per line (although I think that might be a tad low), as going beyond that affects people's concentration due to being forced to move their heads while reading. If you look at a site like Sportsnet.ca along with many of the news sites, that seems to be how they do it as well.
It might also be a good idea to either use a different font or font weight for the block quotes, or put them in italics to help them stand out better. The color of blue in the links on the content could probably be a little darker, maybe closer to the block quote blue bar.
Interested to hear what you think on some of the ideas, as I'm trying to improve my skills as well (non sports related sites) so hearing from various sources and opinions is helpful.
