I didn't think Assuncao beat Dillashaw the first time around. As I recall, Assuncao didn't really do anything to merit winning the third. A case could be made for TJ winning it, but nothing significant really happened, so for me it was a 10-10, with 10-9 for TJ being a possibility.
Regardless, TJ learned a lesson from that fight and has looked much better since(obviously), so I feel like it was somewhat of a blessing in disguise. Hopefully the UFC doesn't pull a Bellator and TJ gets a chance to avenge that loss in his next fight.
