Coming out, Leaf had as good an Arm as I've ever seen. Of course, that was not him as a Cowboy but he could throw the ball.
I'd have to say that Bledsoe was right there as well. I mean, when he was young, he could bring it pretty good and he could even throw it pretty well in Dallas but nothing like when he was young in NE.
Cunningham could really throw when he was young as well. Very nice arm. He could still throw when he came to Dallas but, like Bledsoe, it was not like before.
Troy, well, he could bring it. He could throw passes in spots that you just couldn't beat. The thing he could do was throw that out and throw it with such velocity, such timing and such accuracy that you couldn't defend it. Lots of guys can throw hard but none of them could throw hard and accurate like Aikman IMO.
