I decided to move the roster updates off the top page of the site in order to keep the news updates showing for a longer period of time. You can now access the last 10 roster updates via the right sidebar. You can also view all of them by visiting the Roster Updates category of the site (you can find the link to this category in the right sidebar in the "Various Handy Posts" block).
I may also end up doing this with the game summaries, although I'm still not 100%. If anyone has any thoughts on how I can organize the information so that it's easier to find / read, please let me know.
