Of course you don't see how what you said is dumb. Let's look at that statement again.
"i honestly think it is better for us to get as bad position as possible this year, so we can get another good draft pick next year while there are a bunch of good players"
Oh, boy. There are a lot of implications in this statement and you are completely ignoring several realities of the NBA.
#1. The team is already developing Hayward, Burks, Kanter, and Favors. That is a lot of youth. At some point all that potential just becomes an anchor holding the team back as there aren't enough vet starters to help the kids learn how to compete as a team. Without this vet presence the team develops a losing culture and before you know it all those young guys' rookie contracts are up and they GTFO as fast as possible. Whoops now we are a farm team perpetually looking forward to the draft. It is never a good idea to have a 6-7 player rotation of almost everybody being rookies to 3 year players.
#2. Tyrone Corbin. Maybe you missed it but the Jazz have a new head coach. The hardest part of this job is establishing a culture and convincing all these millionaire players to buy in. It doesn't take a lot of imagination to see that losing a ton of games in his first full year would make it even more difficult to establish authority, and ultimately would cost TC the job. So yet again in 1-2 years we will be looking at trading away players we have developed but can't keep and looking for a coach to clean up the mess. It is really important to give Corbin the tools he needs to succeed or the Jazz will never know if he can coach the team into a contender.
#3. Tanking the season would have no effect whasoever on the Golden State pick. If the team does well Utah almost certainly will still have a lottery pick. Also purposely putting the team in position to lose a ton of games will kill the fan interest, particularly after a lockout. It's utterly unfair to everybody to lose games on purpose.
I suppose none of this really matters since your comment reeks of obfuscation anyways. All you really care about is getting Jefferson out of the way so Kanter doesn't have to earn a starting spot. You know this would hurt the team's ability to compete so here comes the losing = good thing reasoning.
Go to your room.
