The Utah Jazz are not better then the Los Angeles Lakers. There are no superstars on the Jazz at the moment, while the Lakers just got Kobe back. If the Lakers get back to 100% health, they are a much stronger and faster basketball team then the Jazz are now.
The Las Angeles Lakers are historically one of the greatest franchises in NBA history. Sure, Kobe Bryant is getting old, but he is still very talented. The organization has lost great players and not missed a step in the past. The key is the management, they fill the team with good people so that even when they lose the great players they still have enough talent for people to want to play for them.
