You're not going to believe this (ok, you will), but the game actually tracks checks per player (like goals, assists, shots, PIM, and checks per player!). It just doesn't display the checks stat.
As was said before, the offset for the array holding the home team players' PIM counts is 60488.
If you just jump ahead another 26 bytes, you get to 60514, and the checks per player counts are stored there.
Home player checks: 60514 (array of 25 bytes, one for each player)
Away player checks: 61382 (array of 25 bytes, one for each player)
