We are not talking here about the core players of the Lakers in their prime. Even they will play healthy all season, we can't conclude that "nobody" can able to stop them. Maybe I will agree with your statement if those players are in their prime days. I'm not seeing the Lakers as the best contender this season, honestly even the Brooklyn Nets. There's no unstoppable team right now based on my own view and we might see competition to at least 5-6 teams that deserve the Larry O' Brien championship this season.
I agree.
Any team are capable of making to the playoffs or even the Finals. Look how the Suns are so close to winning a championship last playoffs, and they aren't even expected to make it to the Finals.
I guess the era of superteams is over. Underdog teams, composed with perfect complimentary players could actually beat the superteam now.
Even the GSW is scary this season. Especially If Klay plays the same energy after the long injury.
