"Why is everyone putting exum in this worlds team, he's way to young and inexperienced, to play at this level"
2004: Bogut, 19 years old, leads Boomers in rebounds, 2nd in points.
2008: Mills, 19 years old, leads Boomers in points.
I personally think Exum is not at the same level of dominance that either Mills or Bogut were at that age, not as polished, but I've seen enough of Exum play junior world competitions to see that it would be foolish to not give him an 11th/12th spot at least, especially as he is projected as a top 5 draft pick. Like Bogut in 2004 and Mills in 2008, he might surprise and take up a big role on the team.
Worst case, he might end up being a 1998 Drmic, a 20-year-old selected as a 11th/12th man based largely on potential, who never made the Boomers again, but so what? (For the record, I didn't think that selection was a mistake then or now, as I was an advocate of selecting Drmic in subsequent Boomers teams; same with Dwight).
"How about thinking about the fact that the guy has a 12 million dollar contract per year to consider and has in the past repeatedly defied his clubs wishes to play for us."
I view this the opposite way. To me it shows how great it is that we have guys willing to risk and sacrifice their salaries, who are far less financially secure than Bogut is. Bogut is set already. Anyway, he would have to be insured to play, so the "12 million dollar contract" argument is a bit of a distraction. The injury concerns, coming back prematurely, that is a totally legitimate reason to not play. Wish he could though. The Boomers would be totally different with him on the team.
