Veleno is going to be a great pro. He's never going to be a huge point generator or breathtaking offensive talent, but a lot of top guys will love playing with him. His style is going to facilitate things for top end guys. The video does a great job of showing the difference in his confidence and assertion levels in GR pre & post WJC.
No surprise as his whole junior career was finding his feet before slowly cranking it up, and I expect his pro career at each level to be similar in terms of progression
