It’s way too early to say that. Other guys have had rocky starts in their career. Now I will say he’s been brought along too quickly.
I would say the fact he put together a four fight streak was a good sign but almost nobody who becomes anybody goes 4-3 in their first 7. Also all 3 of his losses are brutal KO finishes, dudes that go 4-3 with close decision losses get written off every weekend. Hot prospect or not you can't keep taking that kind of damage.
Hopefully he proves us all wrong if that's what he really wants to do but they really do need to stop feeding this kid to the wolves, just start matching him up with mid-level guys that have records similar to his.
He's part of the problem though as the interview after his last loss indicated he still thought he was better than his opponents and was calling for more top tier up-and-comers. Hopefully a sense of reality is settling in for him now and he will see what needs to be done to get his sealegs under him.
Everybody hears the stories of those guys that destroy everybody in practice but fail to shine under the bright lights. Hopefully Pico lives up to his promise.
