I ended up creating two new classes, one specific for working with the individual rawstats - it takes the dictionary entry of a specific season's stats in the dictionary format that it's stored, and returns it in a format ready for display - and a class that takes a player's whole statistical history and will return it (using the rawstats class per entry) depending on the restriction applied - all stats for all leagues, all stats for one league, all stats for one league in one year, all post-season stats for one league etc. as well as generate the 'career totals' row on the bottom.
The end result is much the same as what I had before these two classes, but the amount of code needed was much, much less and is much cleaner. Thanks Radii.
