I'll just take that as I'm right. It's an unspecific worthless phrase that "dumb people use to seem smart".

I can understand that you're desperate for a win anywhere you may find it Pop Pop, but the simple truth is that you're forcing obtuseness because, well, I'm not really sure why, maybe a misguided effort to appear staunchly objective because you think that gives your thoughts more weight?

Anyway, "repeatable arm talent" is simply a descriptor of "arm talent", specifically that it is "repeatable" and not uncommon or the result of a fluke. For example, Caleb Williams has the talent to deliver the football into tight windows with pace, from different throwing platforms (running, off-balance, etc.). That's the "arm talent" part. Mitch (Pro Bowl QB) (Pro Bowl QB) (Pro Bowl QB) (Pro Bowl QB) (Pro Bowl QB) Trubisky and Justin Fields, at times, showed similar "arm talent", in that they made throws into tight windows with pace, sometimes off of awkward throwing platforms. With Mitch and Justin, though, those instances of "arm talent" were far less common than with Caleb Williams, in fact, oftentimes throws necessitating that specific arm talent, resulted in throws sailing into the arms of defenders over the top (Mitch notoriously sailed passes, Justin less so but it was still there), because the slightest change in arm angle or shoulder tilt meant that neither could re-adjust what they had to in order to complete the throw accurately while maintaining velocity.

Caleb Williams, however, has shown the ability to not only make those throws, but make them much more consistently, or to use another word: repeatedly. The arm talent, again which is into tight windows with pace from different platforms, is more repeatable with Caleb than his predecessors, therefore he has "repeatable arm talent".

If this doesn't help I'll get to work on a coloring book for you.

I've proven to you mathematically that Caleb Williams can throw the ball harder than Justin Fields. His ability to put the ball into tight windows is unquestionable to anyone with a functioning TV and/or brain.

Is that it?

Caleb Williams has the talent to deliver the football into tight windows with pace, from different throwing platforms (running, off-balance, etc.)

Caleb Williams has the talent to deliver the football into tight windows with pace, from different throwing platforms (running, off-balance, etc.)

OK, that's the explanation and boy oh boy was it specific. It went from, in my coloring book head, taking a shit every morning like clockwork as a repeatable talent to... in the pocket, under pressure, on the run, and off balance throws to tight windows.

Everybody works on that, a tiny few accomplish that. I can name only two off the top of my head. Montana and Mahomes. Brett Favre maybe. He missed the tight window in a repeatable way sometimes.
Feel free to get out the crayon and draw it out who I'm missing besides the OBVIOUS Caleb Williams and his half a dozen to a dozen tight window throws.

Maybe someday he'll have the balls to throw them more than once a month and you will be RIGHT.

He's done it in numerous games numerous times, hence the repeatable part of "repeatable arm talent".
