I said that about James looking rusty in preseason (note, the particular game I was commenting on he was with no Westbrook or Durant and finished I think 2 for 17 but with 7 assists and 7 boards). And still I'd take my "chances" that he figures it out again (it was mostly just him trying to integrate mid range shots into his game, particularly out of pick and roll which he typically hasn't done much ever) over taking the chance that Kevin Martin can be healthy (he has missed 20+ games 4 of the last 5 seasons) AND that he can up his % by 9 to match James.
Passing the ball to James and passing to Kevin Martin are 2 completely different propositions. In the later, you are conceding, guaranteeing, that Martin is going to take a shot, and basically 3 out of every 5 of those will be a miss.
Lamb is a huge upgrade defensively to James obviously right away. We do have some potentially stellar athletic lineup, it used to be Russ/James/Perry/Kevin/Ibaka that I thought was that lineup (they played it for like 90 seconds together one preseason games), but now sub Lamb in. When they want to that lineup can lock down defensively. Don't like Perry Jones 3, fine make Liggins the 2 and call Lamb the 3.
As for James and the finals, there was that rumor that he was upset after game 1 (the only game OKC won) about his shots and minutes and Fisher and Perkins had to talk to him.
The Rockets will still have money for 1 more max guy next yr. So Lin, Harden, Parson, Jones, and Asik with D-Mo and White off the bench tentatively, depending on who the max guy is and then moves someone else to the bench isn't bad at all
The damage these 2 used to do when they were on the court together, particularly against all bench units. Kevin Martin isn't good enough of a passer to mimic James's role in it, and Asik isn't clever enough of a ball player nor has the hands to be Nick's role in Houston
