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.
Well, thats pretty much what they've done with Flacco.
I'm not totally sure if he's arguing that a system can physically make a guy more accurate, or like you have said, mask it if he's not.
