Both articles consider the 5th year. They both use $118M as Dwight's LA contract. But that's moot since clearly finances are no longer a driving issue of our disagreement between Houston and LA. So turning to the basketball side of things:
D'Antoni's system does not utilize a post presence like Dwight whatsoever. Dwight wants to be the featured player of the team, but the Lakers can't offer that as long as D'Antoni is running the show. Meanwhile, in Houston, they are in prime position to create a team similar to Dwight's Orlando Magic days, where they load 1-4 with guys who can shoot while Dwight will be the featured interior presence.
Kobe is Kobe, but he's 34 and just coming off an Achilles' injury. I don't think people understand how damaging an Achilles' injury truly is, particularly at that age. Look at Billups. He was already on the decline, but after his Achilles' injury, he basically fell off a cliff. Kobe is a warrior and works harder than just about anybody. However, you can't deny that it's far more attractive to play alongside Harden, who is far younger, much more efficient, a more willing passer, and one of the emerging stars in the NBA.
As soon as Nash left Phoenix's magical medical staff, age quickly caught up to him. He's still a great floor general, but his effectiveness is now limited to only about 20 minutes rather than 30-35. Lin is not the best PG you can have by any means, but he's still more than serviceable, and his strengths cater to Dwight. He's great on the pick and roll and is an underrated post entry passer. If he could make Tyson look good on offense, imagine what he could do with Dwight.
Artest is still a great defender and last season he showed his offensive game is still intact, but he's 33 and has no where to go but down. Meanwhile, Parsons has emerged as one of the most promising and dynamic wings in the league. It's an added plus that he's close to Dwight and has been in constant contact with him this whole offseason.
LA has no room to bring in anyone else this year. Next year, Dwight and Nash will be the only guys on the books (with Nash being an expiring). 2014 has a lot of high-profile players slated to become free agents, and the Lakers have always been a hot free agent destination. They certainly have a chance at surrounding Dwight with two more stars. The problem is Houston ALREADY has another star, and they too can bring in a third with proper maneuvering.
Then you look at management. Morey was able to convert Lamb and some draft picks into Harden. He was able to find Parsons in the second round. He successfully stole Lin and Asik away from their former teams (although Lin's contract may have been a bit excessive). The Lakers have traditionally had a great management, as well. But how has their track record looked ever since Jim took over for Jerry?
