I just wanted to post back here because I did make some adjustments based on your feedback. I added some more Sabermetric stats to the site - most notably FIP, wOBA, and OPS - in addition to BABIP, which was already present.
Thanks for the feedback, it was definitely helpful! If you guys come up with anything else that would make things more usable for you, please let me know. I'm working on the site pretty actively right and I'm definitely looking for suggestions on how to improve things.
