They aren't a contender because they don't score enough.
Just like Boston wasn't last year when they were the #1 ranked defense and ranked #24 in offensive eff.. And every team we play seems to score around the same amount we score, meaning they are playing into our game. Its a lot harder to be a great defensive team, than a great offensive team. Memphis just has to get hot at the right time.
I didn't see Memphis play Miami, SAS, LAC and OKC and say "we are far away from beating those guys." We actually beat 2 out of 4, lost the other game in a BS OT match and lost to LAC in the 1st game of the season. To act like those teams don't have their own problems and make it seem like we have all the problems doesn't seem fair. If anything, OKC looked terrible against us because they Harden is really who hurt us the most when he was paired with KD and Westbrook.
We can go to war with any of them in a series. Who's stopping ZBO and Marc, if this team ends up shooting the ball at a decent rate and can get a guy that's capable of attacking the rim?
