I am writing this on mobile and with a time limit so I apologize in advance for its quality and brevity.
much has been made on this website and countless others, of the large weight difference between GSP and Anderson Silva. however, i feel that many journalists and fans get the wrong impression about the size difference. Anderson admits he gets large inbetween fights on the last primetime he stated he was around 210-215. Today gsp threw out 234. these numbers are all misleading.
Lets first start with GSP he says he is around 188lbs.Using google, the source of all true knowledge I came up with body fat levels varying from 5.5-7. According to gsp himself he weighed 189 during his koscheck fight. A coach for GSP said they planned on rehydrating to 193 on fight night. lets take the highest body fat number at 7% and calculate the lean mass of GSP at his lowest weight in his past 3. we get a lean mass of 174.84.
For anderson silva we have numbers via tatame. out of season 213 lbs 19.1% body fat. and 2 weeks from chael. 9.2% and 198. the first number was off season but i believed they used water displacement when i am almost certain the second wasnt using that method which if i recall is the most accurate. anyway we find that anderson has 172.32 lean body mass off season and 178.6 2 weeks from chael. i am assuming the discrepancy in lean mass is from a pound of muscle or 2, different methods of measurement and different times of day, or some combination of those and other factors.
Almost every single mma journalist believes jon jones and andy are closer in size. A fight shape andy was as low as 194 for demain maia and 198 for chael. Jon jones weighs around 220 now and is way less than 10% body fat. So lets give him the smallest he ever weighed and a huge body fat percentage. 215 for shogun on fight night and 10% body fat.. which is crazy. That would be 193.5lbs of lean mass.
You see that no measurement has Anderson having closer amount of lean body mass to jones. When in shape andy is not a big man. When out of shape he is a chubby one. If gsp will only fight at 170 thats fine. But, as far as i can tell he is either being purposefully misleading or is horrible misinformed. I will add sources later. Both of my anderson numbers are from tatame and my gsp numbers are from bloody elbow articles. Thank you to both websites i will properly source soon and edit for grammar and mechanics errors. Sorry again.
