Something which'll add to the game, but may be a lot of extra work (which is for Mike to decide) :
I'd be very interested to see how a breakdown of the round's action ie shots thrown and landed, and each fighter's energy levels in between rounds. Similar to the post fight stats. Perhaps simplified into total strikes thrown and landed, not the full head, body, clinch, takedowns data etc etc etc.
Obviously it would be too late for a manager to change anything whilst reading but it would add to the nervousness and interaction during a pbp read-back.
A graphic could pop up, like you've been handed a sheet of paper with some stats written on it.http://i58.tinypic.com/5fi3x1.jpg
(try and ignore my limited graphics skills - MS Paint is my level. and yeah I can't rotate text in that.)
Perhaps it could be a feature only available to people who have a PA; another little benefit to having one.
