Garcia would probably weigh about 13 pounds more, which changes things Ortiz is 10 times the fighter, though... a masterful, versatile guy
If you give Ortiz a 24-hr weigh in, then you can assume he puts on a bit of extra pounds too. Besides, Garcia isn't a pressure fighter who imposes his size. He's a counter puncher.
We can play ifs all day, the bottom line is that Carlos Ortiz actually weighed 135 and 140 when he was fighting... Danny Garcia in Ortiz's time is a full-fledged welterweight or even a Junior Middleweight... They aren't actually fighting in the same weight classes
