Her change in approach and tactics is the problem. She's more tentative than ever and has adopted a point style. She wasn't sitting on her punches as much against ribas and she was having an oddly difficult time finding ribas at times, even over extending at times. She also wasn't kicking much. She was there to touch on the feet. Time takedowns, sit in guard, go body body head, and ride out a decision. Watch how she fought and listen to her corner. It wasn't lack of power -- it was her style that she's been using lately.
This fighting style is becoming a trend of hers. Her last fight at 115lbs was even worse than her last two at 125lbs. Hell, even her last win at 115lbs was a close split decision that she squeeked out with some ground control again.
I'm not one of the sherdoggers that bags on pat and their relationship, but his coaching lately is leading her to a lot of fights like this one, and that's not the best rose can be. She's going to lose another close fight soon fighting this style. It's like she forgot that IT'S A FIGHT, you know what I mean? The problem is how she's approaching fighting recently; it's not the weight.
I'm repeating myself, but this is where rose is at, regardless of the division.
