Sure you do. You trade for John Collins' contract and hold it as an appreciable asset, while playing him at the 5 knowing full well he can't guard the rim. Win-win.
You think the Jazz being far-and-away the worst defensive team in the league just happened by coincidence? If the front office really wanted to win games, then wouldn't you have to conclude that they're just completely incompetent?
You can't act like a team that finished its season 5-25 wasn't actively trying to lose games.
We started the year playing Collins as a PF, and THT as the starting PG (and Clarkson as a starter, no rotational minutes for our better defender in Hendricks, few and no guaranteed ones for Simone and Ochai that were the best after).
All much more tanking moves than playing Collins as a center (still average at best, but average isn't fighting for the 1st pick overall, which was the case when we started the year 7-16, or 4-11, basically 25 and 22 wins pace), where he can actually positively impact on offense and somehow isn't worse defending than as PF (even along a traditional shot blocker as the center, as he's even worse defending the perimeter, or in space, whatever definition one would prefer to go by, than protecting the rim)
When we started moving away from that, we started to win games, and that ****ed up the tank (we had to take the turn we did to still have our pick). The reasons why we did so, that could be up for debate (as the reasons why we tried that we tried to start the year). Agents politics, injuries, players we had more belief and wanted to prop up the value than others, etc...
