The 2019 NBA Draft class is a pretty strange one all things considered. There is a clear cut number one (and maybe number two at this point), 6-8 guys in the next tier and then maybe 30+ guys that could presumably be in that third tier of players. For the Dallas Mavericks, that would mean they are all but guaranteed a guy that they should be high on by pick number 37.
With the whole draft in shambles once the top 8-10 guys are gone, there is no telling who may be available for the Mavs at pick 37.
