No, i'm not.
No Kiwhi means no chance at a le...and the outcome of the last games till now suggest that, as a young talent level, with no Kiwhi we are not a play offs team.
We had a wonderful schedule, the best till now...now cames the worst part.
And experienced people like Manu and TP knows that...
Coming to the single players.
No chance at a le, for a veteran, means less enthusiasm to play.
Alridge has already accomplished his main goals (being at the All Star game and show he is still an all star player and deserved his contract...thatn as of now looks like a good contract). So no chance at a le means he colud start thinking to better preserve his body for next season.
Manu is showing the normal pains of an aged body who's being asked this year to carry the load more than his body can, and his contract is for another year...so its logical he's gonna think he should better preserve the last energyes for a last run next year than for this one. TP and Gay both come from a bad injuryes and have already shown that, if healed, they can contribute some...but at this point is logical they're gonna think is better for them ton treat their bodies well and avoid further risks of re-injury. Them both, like Pau, are veterans that understand is better to preserve their body for a real run next year (Pau is under contract, imho Gay is gonna pick up his option and Tony will be given some years at the minimum a la Manu as a point guard reserve role).
Green has a weird situation in the sense that's true he's playing for a contract, but its also true that his nagging groin injuries have been recurrent this year, so he could also think that's better not to play too hard with his body... if he's gonna injure himself he has only the chance to opt in next year (p.o. year).
Mills is playing like this year...and his enthusiasm this season has probably been more for the table (I mean for eating and drinking stuff) than for the court, thanks for the summer contract he signed.
You are right that the young guns (Murray, Bertans, Forbes, Jolo, Kyle, White, Paul) should be enthusiastic to exploit the opportunity to play, but none of them, except for some games, till now has shown enough talent to carry the team or be considered a potential future star...and they can't be asked too much. So their enthusiasm, considering the situation, also if present and big at the beginning, is gonna be limited game by game.
