If anybody wants to redesign the player pages, I'd be all for it. But like rrenaud, I'm pretty busy with other things, like Dominiate.
My ideal for the page would be a few "previews" of things you can look up about the player, plus links to "More info".
So, for example, you get their most recent 3 games like you do now, then a link to the game search page. The card stats section could have a list of their 5 best and 5 worst cards (by win rate given available, which I think is the most reliable statistic if you correct for low-frequency outliers), and then link to their "popular buys" page. The achievements could show a few recent achievements, and then link to the full list.
This isn't just for aesthetics: these pages are starting to take a ridiculous amount of time to load because of how much data they have to pull out of the DB.
