Lara would whip his ass right now. However, Andrade has such great height and physical gifts that he may have just as much long term potential, which is saying something considering how highly regarded Lara is.
Lara blows him out of the water right now. I think Lara probably has the edge long-term as well, even though Andrade is much younger. Honestly, I think Andrade's style puts some serious limitations on how far he can go. He has good athleticism, but not good enough to get away with a style as wild as his at the top levels.
Right now? Lara by knockout. But Boo Boo is very young and has a lot of potential, who knows, he might be the best US prospect turning pro in the last couple of years. But then again, Lara is a superb prospect as well and fights if he had 20 pro fights before, too much for Andrade at this point, maybe too much at any point of their career.
Lara should be favored, especially given that Andrade is just starting in the pros. I'm a big Andrade fan however, so i gave him a sympathy vote.
