Knickabokkaz, your insistence on thinking the rules don't apply to you is wearing thin. No one is exempt from the forum standards--no matter who they know. Daryl Morey himself would have the same responsibility to maintain forum etiquette.
Now, getting to your post...you are neglecting one thing in your defense of Lin and his lack of reps with Howard. An elite PG wouldn't need any reps to succeed with Howard. He would get on the floor and look to set up the big man and would do it well. Paul, Rondo (when healthy), Rubio, and a handful of others would not need practice to do this. It is PG 101. These guys don't grow on trees and there is a reason their respective teams cling to them tightly.
Check out Steve Nash from 2010. He forces the defense to shift and then either hits a cutter or finds a shooter wide open in his spot. That is what an elite PG does. That's Jared Dudley and Robin Lopez he is getting easy buckets for. Imagine Parsons and Howard in their places.

Having said this, I will defend Lin by pointing out he is no PG. He is a combo guard (who is often listed at the point) and should not be held to the same standard. But that's the thing. It wasn't an attack on Lin. It was a question about what makes Houston a better team...and Rahat is right. I like having Lin on the team, but it is becoming increasingly apparent that a player who can elevate the play of all around him by getting them easy looks would be huge for this squad. With Howard, Jones, Parsons, Smith, Casspi and Harden all extremely capable finishers inside plus our group of three-point shooters (currently floundering around league average on the whole--but that's the point--they aren't getting the best looks which an elite PG would facilitate) a pass-first PG would boost scoring and efficiency across the board.
BrentYen, the difference is some guys just have a knack for catching the defense in mid-shift (when they are weakest) and delivering a pass that leads to easy scores because it leads the player towards the easy score. It is what I would call a true assist versus the categorical ones that get counted because you were the last guy to pass the ball before it gets shot. If those stats were kept (publicly--as I am sure someone tracks them in private) you can bet guys like Paul and Rubio would excel at it. It is akin to a pass play in football. Yeah, most QB's can hit a receiver for a completion, but the really good ones hit them in stride and those more often lead to TD's. It's the same thing in basketball.
Take note of all the times Dwight has amazing post position and seldom receives an entry pass because the ball handler simply does not have the skill, nor the confidence, to send the ball in before 3 seconds would get called. Ultimately, Dwight has to retreat outside of the paint and then gets the pass a solid 12'-15' from the basket. This increases difficulty by a mile (as has been discussed) and subsequently lowers efficiency.
