Female boxing sucks. At a minimum they need to fight 3 minute rounds and probably use smaller gloves. Shields is arguably the best female boxer ever (not sure I agree with that) and she has like 2 or 3 knock outs in 12-15 fights. She can't punch her way out of a paper bag.
My solution to fix women's boxing and even make it a great watch would be to have them box using UFC/MMA gloves and UFC/MMA round schemes. 3 x 5 minute rounds for non title fights and 5 x 5 for title fights. In the event of a draw in a championship fight, one additional 5 minute round.
