You can improve in the margins, but that's about it. Think of it as moving within letter grades. If you're a B- level passer, you can become a B and maybe a B+, but a guy with B- accuracy is never going to be an A rated trhower and a person with C level accuracy as a rookie is almost certainly doomed to a career of mediocrity.
That said, the right system can mask it and I think it's the exact opposite of the system most would advocate. If only half of your balls are going to be accurate, might as well launch it downfield and make them count.
The short passing game should be utilized by truly pinpoint passers. I honestly think that your more scattershot arms should become downfield bombers. That's what finally made Eli effective and that's when Stafford was at his best.
Geno's accuracy is such that a smart coach will make him a guy that thrives by absolutely picking teams apart in the 10 yard range.
I disagree with the part in bold because, as you said, accuracy is all about bio-mechanics and repetitious motion. If you lack the ability to throw 10-15 yards accurately, you'll really notice when you stretch that pass out from 10 yards to 20+.
I guess what you are getting at is if it's going to be a crap shoot of a pass at 10 yards why not go for broke and gain chunks at a time, but we all saw what happened when Cassel tried to bomb it away. He either threw incomplete by over-throwing, got it picked or damn near killed his WR by under-throwing it.
