Depth does not automatically equal being good. It just means there's not a large drop off between the starters and the bench, but other teams could have much better starters but a weaker bench but the starters are strong enough to make them a better team. Just speaking in general not saying this applies to any specific teams. All things being equal depth is better than no depth but it's hardly the only consideration when it comes to best teams. Just like talent alone does not win games just look at memphis for an example of this. Tons of talent, but low BB IQ and terrible coaching = crappy team.
