Yeah, by your definition the Dubs are the sole contenders... and they would've been last season too. But that's why games are played. Stuff like injuries, slumps, bat matchups, etc happens. I remember when the Mavs won, they were totally legit post-facto, but if you look at their regular season, they weren't a sure thing. They just caught fire at the right time, built some momentum and ran the table.
You can tell flaws on a team here or there, but can also hide them against the right matchup. Which teams you end up playing are also breaks. I see people worrying about playing the Clippers again, but you really can't worry until you get there. Maybe you catch a break and you don't have to play them, you worried for nothing. Just let things play out and see what happens, it's not like we as fans can do anything about it anyways.
