Ok, I'm biased as hell because responsive web design is my bread & butter.
I also see all the moving parts from the other side of the equation, templates, dynamic content, and yes, the mobile devices. So take my opinion with a big ol' grain of salt.
But, I really like it.
The hierarchy of information is clearer, the calls to action are well thought out, each element has it's own breathing room, and my my machine at least, it runs a heck of a lot faster. They've also avoided the "100% line length" on body copy, which drives me up the wall when I see it.
I particularly love the background rollover, and tickets/gamecenter calls to action on the
scores page, that's the "wow factor" for me.
But there are pain points, the
teams section seems like it was an after thought, it's nice to have site|news|tickets|roster|shop for each team on that page, but to the detriment of usability as you're required to scroll down to find any single team. A 3-6 column grid with a 1-2 CTAs for each team would be easier to scan.
Likewise the
players section seems to be riding the current tumblr/facebook/linkedin trends a little to hard. It's a design that might work for a single team of 24 players, but doesn't scale well up to 700+ for the entire league. Sure Crosby & Ovechkin are up front, but unless you dive into the search, you wouldn't be at fault for thinking there's only 10 players in the league.
Having said that, when you drill into an
individual player's page, there is a lot to like there. Although some of those cards could have been divided into a 2 column layout.
Anyways, as a web designer I'd give it an 8/10, but as I said, my opinion is tainted by my development knowledge. Which should never trump the end user.
