I could easily see Lakers as the best team in the league.
If Pau is the way he was before he went out of steam last year.
If Kobe healed all the little injuries.
If Bynum's ok.
A lot of ifs but it's not unrealistic. They were the most tired / burnt out team last season. They had their rest.
Dallas didn't exactly got stronger. The rule changes might hurt Durant big time. I'd still bet on Lakers as favorites in the West. And if it's Lakers-Heat, and Lakers big guys are healthy, Heat will be in trouble.
