Baryonyx walkeri v Jaguar

I'm pretty sure that if you scale massive animals down to less than 5% of their own body weight, their agility will be affected greatly (how exactly I am unsure). Also the jaguar is particularly strong/robust for its size, unlike theropods which although strong for their own size, simply cannot much the pound for pound strength of a jaguar, it is a much smaller animal and the square cube law allows smaller animals to be more compact whereas larger animals must have less centred/more spread out levels of proportional muscle mass simply due to their size.
