Yeah, when I watched it I felt the same way "that was awesome, but in an MMA fight he just got countered/taken down/whatever." I would have loved to watch Bruce fight MMA. I don't think he would have never lost, but his blinding speed and power, mixed with his excellent precision and insane athleticism would have been amazing. I don't know what his history with ground work was, but I imagine being the martial artist that he was he would have been pretty open to really learning and perfecting the popular styles we see in MMA today.
