Elkins is actually a much tougher opponent than what most MMA fighters make their debut against.
Definitely some holes in Shield's grappling but it was expected. She actually showed a lot of promise. Some of the positions she got herself into was a result of what she did as opposed to what Elkins did. On the feet, she looked phenomenal, granted it was against a grappler. Shields is the best boxer to ever transition to MMA. Holm was an excellent boxer but transitioned to MMA when she was already in her early-mid 30's and in boxing she was never particularly fast or powerful. Although Shields lacks power, you can tell she's got very fast hands. She's gonna be a big problem on the feet.
What I was most impressed with was the heart, determination and gas tank she showed. Many experienced MMA fighters are gassed after 1-2 rounds fighting the way Shields fought. It was a great performance against a fighter that couldn't have been a worse matchup for a striker with minimal experience in grappling. If Shields fought Elkins again in 6 months, Shields would batter her in a couple of minutes.
I'm intrigued, I liked what I saw.
