Not my logic at all, I just know a team's weakness when it's clear as day. Those PGs can't stop eachother nightly, but they produce enough to offset eachother's production on the offensive end. If Westbrook scores 30 against Tony Parker, but Parker comes back with 24 of his own and manages to break down the defense time and time again, it's a draw. We won't get that from Steve Nash at this point in his career. He can't penetrate as effectively as he did earlier in his career, he's even slower than he was 3 years ago, and the PG position has vastly improved in the last 3 seasons. He can't produce at a level offensively to offset his deficiencies on the defensive end of the floor.
We've always had trouble defending the P&R and it is only going to be magnified in the upcoming season with our horrid defensive rotation at the PG slot and no legitimate defensive anchor to cover the paint the majority of the time. Dwight Howard gave us excellent coverage last season and during our title year, Bynum/Gasol/Odom were capable of rotating and contesting the majority of drives into the paint. We don't have that kind of personnel anymore.
The one-on-one post match-ups are irrelevant, that's not going to be our issue. The center position too weak offensively to worry about that. Or issues will be stopping penetration because we don't have capable perimeter defenders or help defense in the paint. Kaman and Gasol won't be able to stop drives into the paint whenever we go up against a quick PG capable of breaking down our perimeter defense. That label applies to nearly every starting PG in the NBA today. Things looked bad last year when Nash would get beaten off the dribble consistently, but it was often mitigated due to Dwight's presence in the paint. We don't have that anymore. Instead we have two 30+ year old centers who are slow on their feet and incapable of being defensive anchors at this point.
Above average post defender? Is it 2010? Pau Gasol hasn't been capable on the defensive end of the floor since the middle of the '10-11 season, then he fell off a cliff once he began to shy away from contact in the paint on both ends of the floor. On the defensive end, he can't even compare to his brother. Marc Gasol has MUCH better defensive instincts than Pau, is the better help defender, is the better post defender, and in all honesty he is the better player at this point in their careers.
Memphis has capable defensive players on the perimeter, that's the difference. We don't. You can't just point to Nick Young, Jordan Farmar and Wesley Johnson. Players need to have the defensive mentality to make an impact on that end of the floor, it's not simply about their physical gifts. Mike Conley is very quick and capable of keeping up his man in isolation and is very good at fighting over picks. Tony Allen is one of the best defensive players in the league today. Tayshaun Prince, despite being a shell of himself, still has the defensive smarts and dedication to make some impact on that end of the floor. These guys all have a defensive mentality, we don't have a single player on this roster like that aside from Jordan Hill. Not to mention the fact that they had a coach that preached defense and made it a priority for their squad, a far cry from our situation.
We don't have a half-court defense, that's the point. This is the first time since '07 that the Lakers haven't had a legitimate defensive anchor waiting in the post. Pau can't play that role, Kaman can't play that role, and Hill can't be relied upon for major minutes.
There is no magical "Oh hey you're a Laker now!" clause that transforms players into serviceable roleplayers. We've already had Farmar on this team, I've seen enough from him to know that he's not very good on the defensive end at all. Unless he somehow had a complete career transformation playing against inferior competition, he's not going to be a factor for us defensively. Nick Young has no desire to play defense, at all. Nick Young has never shown an interest on that side of the floor, he's always been a chucker with some of the worst shot selection in the league. It's not just simply a player having the physical tools that leads to them being a solid defender, they need to have the mentality as well. Otherwise, every 6'7 player in the league with a good wingspan would have been a capable defender. Wesley Johnson has the "potential" to be a good player on that end of the floor, but that's all it is at this point. We can't bank on that.
Nash being one of the smartest team defenders doesn't mean a thing when he's incapable of playing solid defense. It doesn't matter if he understands the theory behind it and where to direct his man if he can't do it. He's never been good on that end of the floor, and he's only gotten worse since 2010, the last time PHX was relevant. When was the last time Nash came out on top in a match-up due to his defensive ability? His whole career has been based around out-producing the opposing PG on the offensive end of the floor, and he can't do that anymore. Teams with young, quick PGs will be salivating at the opportunity to abuse the Lakers when they see Steve Nash and Pau Gasol being the only obstacles on the way to the basket.
We don't have the talent to cover our defensive deficiencies at this point. When we were winning titles, Pau Gasol was one of the best big men in the league and Kobe Bryant was still the best player in the league. That was almost 4 years ago. Our three best players now are a 40 year old Steve Nash, Pau Gasol whose knees have been nearly grounded to dust, and Kobe coming off the most serious injury of his career. Having a new defensive system won't change a thing if we don't have the personnel to run it.
