I can't recall a single game where all 12 played. Your premise may be off. Malone doesn't play more than 10 on any night. Could be wrong, but I don't think so.
Deep? Uh, no.

I won't repeat what others have said. But, no. And really depth is not really that important anyway. Sure, you want 8 deep. But not 12. Unnecessary. And if you have a good 8 or 9, your 10-12 should be god awful cause most of the cap is spent.
Btw, people forget Landry is almost for sure a part of the future. They just signed him to a 4 year deal. He'd certainly be available for the right price, but as of now, he's gotta be considered a part of the next couple years at least.
I think these last ditch comebacks may be leading people to think we "competed" with these good teams. No, we lost. They got up big, got bored, let IT go nuts (why teams don't double him and make everyone else shoot is a strange thing, since he's the only bench player that really can hurt you), then when the game is on the line, they buckle down and get the W. Happens every night in the NBA. Hey, it's enjoyable, but don't start thinking we are one step from greatness (unless that one step is lebron). And this is of course assuming teams like OKC, Clippers, golden state, etc. aren't half asleep the whole game when they play us. We are not exactly the team these guys get up for. We are the doormat. Bad teams compete with lazy good teams every night in this league. They still rarely win. It's a harsh reality, but it's the truth. The fact we are consistently rallying means we are consistently down big. Not good.
To,whoever said we are competitive without cousins, huh? After one game, which we lost? Sure.
