The Lakers implosion began a few years ago when they tried to trade away their entire bench and Gasol for Chris Paul. They pissed off Lamar Odom, traded him (Sixth Man of the Year) basically for air and a handshake in return, gutted the bench, and then asked Kobe to win with Steve Blake playing the point. That team was so fortunate to get as far as they did (the year they got swept by Dallas/San Antonio...can't remember which). It was terrible.
After that, Dr. Buss passed away and Jim took over, and it's been hilarious to watch ever since. The Mike D'Antoni hire was the worst coaching hire in Lakers history.
Wrap it all up with yours - $23.5M and then $25M for a 35-year-old Kobe coming off achilles surgery wasn't exactly the right move to make. Sure, Kobe Bryant is one of the all-time greats, but you never overpay for aging talent. Kobe should have been offered $15M/year at the MOST.
Now they've taken on a terrible contract in Steve Nash, they have Kobe's contract, and they need to move Gasol. Their best bet is to try and move Gasol to gain more cap space, and then begin to build around Julius Randle. Let Randle know there might not be a ton of winning here in the next few years, but they can add some high energy players. Kemba Walker is a restricted free agent next year, they will be in contention for Kevin Love if they play their cards right, and they might be able to go out and acquire a player like DeMar DeRozan or Rudy Gay, an elite scoring swingman. Maybe even a middle-tier guy like Tyreke Evans.
Basketball is all about the "Holy Trinity" -- distributing point guard, elite scoring wing, 20&10 big. You get those three things and you have a shot at a minimum. Surround them with the right players chemistry-wise, and you have a solid foundation to continue to plug-and-play guys and compete for a title. You can see the teams that are on the cusp or who are good and ready who have the trinity - Clippers, Spurs, Dallas (almost), Bulls (with healthy Rose), Wizards, Blazers, ....almost there are Pacers and Warriors.
Anyway sorry for the wall of text. I just love this sport and definitely understand it a lot more than I do all of the nuances of football. Still learning offensive and defensive line nuances.
