The Bucks have one player over 15 PER (league average), the Jazz have five. That's quick and dirty, but good enough to illustrate they are nowhere near the Jazz talent level.
I just tell you that if the Bucks grab Parker or Wiggins they will become a contender in 2-3 years!
Knight, Antetokounmpo, Middleton, Henson and Sanders have similar talent as our Core5.
In addition, Mayo, Delfino, Butler, Neal, İlyasova, Pachulia...
