This is a great review of the project as well as a little introduction to Joyner Lucas as a rapper overall.
He did come out and clarify that this isn't his debut album, he actually said this is nothing compared to his debut album and I'm definitely going to hold him to that.
As amazing a rapper Joyner is overall funny enough I think the area he could improve on the most is his bars in terms of wordplay, similar to Dizzy Wright in the list you named earlier.
With that said his flows, concepts as well as his storytelling ability put him in my top 3 'underground rappers' to make major moves in HipHop this year.
