I never said Cousins is/was was an agile quarterback but he is not an apt candidate for the far end of the mobility scale. For that distinction I would pick someone like Vinny Testaverde. Guys like Brady and Marino were far from nifty but they could take a strategic step or two to get off a throw. Better conditioning could push Lindsey into that group. Also, as I said before, I think Lindsey will get better at recognizing coverages quickly with more experience and maybe he will have better targets. These will help him get rid of the ball sooner and hopefully minimize the effects of his heavy legs.
