He shouldn't have taken the Norwich job really. Leicester was a free hit.
It's interesting seeing him in MLS, he's probably the most qualified manager in that league but he's also on a hiding to nothing from a success perspective, as Charlotte are still a new team that is trying to establish itself and has spent it's first 2 seasons with crap management and a flawed squad. They don't currently, for instance, have their full Designated Player allocation filled and their 'star' striker is currently being outshone by a youth player. Smith seems to have improved the team and the fan base likes him but he's not going to win anything and by all accounts the owner sacks people for fun.
