In regard to Jimmer, I didn't say he can't be a conventional PG in the NBA, I said that from what I read it doesn't sound like he can be an elite PG, or in other words he can't be the Kings' long term answer as the starting PG if they want to become a contender some day. I may be wrong, but that's what I got from what I read, including your posts.
As for the whole PG issue, I agree that we will have to agree to disagree... I believe the PG position was created for a reason, and unless you are playing a very specific style of basketball (and running it successfully) there is still a huge need for a great player in that position in modern basketball. It is still widely accepted in the NBA that PG and Center are the two toughest positions to fill successfully. Center, because you need to find someone tall and big enough to fill that position, which is rare enough, and on top of that he needs to have NBA level basketball skills. PGs, you can find a ton of players with the right size, but their skills have to be special, both physically and intellectually (for lack of a better word). Bringing the ball up the court and passing it, anyone can do that, but I'm sure you'll agree with me that Chris Paul, Rajon Rondo, Deron Williams, Steve Nash, etc. can do a lot more than that, and that's why they are considered elite PGs, as opposed to Derek Fisher, who can bring up the ball and pass it just fine.
One of the posters here (Lockehead, if I'm not mistaken), said in a thread that this whole "just a guard" theory is a copout, and I completely agree. Being able to play more than one position is a good thing, but you have to be a complete player in at least one position. Westphal telling Tyreke that the position definition is not important actually hindered Tyreke's development, because he was never required to master any position. He does not have the fascilitating skills of a conventional PG, and does not have an off-the-ball game of a SG. If he doesn't develop at least one of those skills, the team will hurt, and this is one of my main beefs with Westphal. He is not pushing Tyreke to define his game in a way that the team can thrive around. Tyreke can do special things, but his incompleteness is hurting the team and will continue to hurt it until he gets proper coaching. Until that happens, I cannot see him as the long term answer at the PG position either.
Whatever you want to call it, PG or guard, the primary fascilitator is the engine of every good team. Currently, the Kings have no engine.
