If you want to show off arm strength it's the ability to drive the ball into intermediate zones without a hump because you're putting enough velocity on it to get the point of the ball down. You're keeping leverage on your throw and can fire it into windows.
It's also the ability to quickly and with a compact release fire a ball into tight spaces. Barkley can't do that, he needs his entire release and plenty of room to move his feet to get balls to come out of his hand with any jump. That's not 'usable' arm strength because so many NFL throws come while under some form of duress or without the benefit of a massive, clean pocket. Barkley doesn't have 'easy' velocity or natural arm strength.
Everything is relative - Barkley can throw a football harder than 99% of the world. However, he is closer to Matt Cassel on the arm strength spectrum than he his Matt Stafford. In the end, his arm is adequate for the NFL and nothing more.
He is not going to be elite or anywhere close to it. He'll be a passable system quarterback that will probably be good enough to get some teams into the playoffs here and there. That's about it.
He has most assuredly not 'proven that he has an strong arm'. If anything, he's proven that he doesn't.
Thank you for saving me the trouble of typing this out.
