Fundamentals and game planning can be learnt, Nunes put things together in less than 1 year under ATT.
But speed is gifted, Pena has a much higher ceiling than Vieira.
Sure, but someone's gotta teach it to her. So far I haven't seen any evidence that she's learning fundamentals & fight smarts, doesn't mean it can't happen, but until she starts showing these things in her fights my current opinion stands.
Are you judging fighters only by their latest fight? I expect better from sherdogers in wmma thread.
Pena underestimated Shev‘s grappling skills and she paid the price. Despite the loss, she avoided Shev‘s counter strikes and controlled the clinch most of time. Pena's performance against Cat is more impressive than Vieira's. She not only defend Cat's top game effetively and also controlled Cat on the ground much better than Vieira.
I'm not impressed by Vieira's performance against Cat at all. Cat has no striking skills and has lost all her explosiveness, yet she still give Vieira trouble on feet in round 3. Shev would lit her up like a chrismas tree. On the ground Vieira's GnP is Mcmann-level weak, and she didn't try to set up any submission move other than arm triangle choke.
I'm judging her by her entire career. Since you mention Cat, if Zingano hadn't derp'd herself a dozen times as she's liable to do, Pena would've been down 2 rounds going into the 3rd and lost the fight. But more importantly, Pena's fundamental mistakes are all there which is how Cat got a bunch of freebie throws and takedowns against her. The first takedown in round 1 is a good example, Cat had double unders and a bodylock, and Pena is standing around on one leg trying to block knees that aren't coming. Then she turns sideways in the clinch instead of flattening herself against the fence to buy time for pummeling under or breaking the grip, turning sideways on one leg completes half the throw for Cat. Result? Easy takedown.
Same thing on the 2nd takedown. They're in the clinch and have over/unders on each other, Cat still has her hips behind her and her body isn't flattened on the fence, this means she can still push forward. Pena is a staggered stance with one leg forward and the other way back, trying to pull Cat off the fence. She then uses her rear leg to try and trip Zingano, Cat simply drives forward and pushes her right over for another easy takedown. By lifting her rear foot off the ground in that stance, she can't lean or push into Cat to keep her on the fence, her balance point is her front foot which was level with Cat's feet, making it easy for her to get pushed over backwards.
This is basic high school wrestling stuff and Pena doesn't get it right. I would probably wear out my keyboard trying to summarize all her fundamental flaws.
Pena can get away with a lot since she's one of the better athletes in her division. She's got speed, strength, a good gas tank, and toughness. The problem is she's relied on her athleticism to the detriment of her skills development. This is unfortunately a common problem in MMA.
