All those things smoz mentioned and...
* display checks per player vs PIM (already done, thanks smoz)
* in-game checks only count for checks per game (thanks smoz)
* after-whistle checks separate stat (thanks smoz)
* fix rosters on teams (no duplicate players in FLA, ANA, etc.)
* fix "superspeed" bug after player misses pass/gets checked
* Change OT length to period length/make it an option
* Fix post whistle penalty shot goal bug
* Expand to 32 teams
* Add 2on2 mode!
* Fatigue rate option for line changes
* Add season mode
* Increase replay length / make it option
* Player card photos for all players
* Separate button for poke check and switch player
That's all I could think about for now.
