The Charlos were always decent to me, but I felt like they were just going through the motions when they were coming up. They looked solid, but not special. I always felt like they could have done more (especially Diet) once I'm done watching them.
Now or maybe the last 1-2 years they've been evolving and slowing beginning to look like beasts and seem special. They still boxing good and using their jab and movement, but now the power and the need to make statements is balancing out.
I think they're great for boxing. Boxing needs personality just as much as it needs fades. Them nikkas giving out both so I'll just enjoy the ride.
