the rookies are being schooled , and whipped into a team.
They NEED TO LOSE some....becasue they aren't going to win every game . So losing EARLY gets this mental colapse of failure out of the way. EVerybody learns to push aside the defeat and move on , pick themselves up and win the next game. Thats how you win playoff series....mental tuffness, it took Lebron a long time to understand the MENTAL part of the game. OKC failed big time.
Also losing show DA and DOC who cares and will come back and play harder next game.
Losses expose mental weakness and a players capacity to focus on the task at hand and the big picture .
You don't want players who quit ...
You can be sure DA and Doc are looking for those who are confident , and won't quit.
