I don't know why non-star Euros go to the NBA anyway. If you can get around midlevel multi year deal in the NBA, it makes sense. If you go to the NBA out of competitive spirit, it makes sense.
But in case Bargs
doesn't get mid level with multiple guaranteed years, I won't be surprised to see him leave. Once you account for taxes, I'm sure he could make more than 5 mil / year in Europe despite his poor last few years.
