Foles will never throw a Dan Marino deep ball. Dan Marino didn't throw a Dan Marino deep ball. The receiver has to adjust and highpoint the ball if necessary. It's just how it is. It's his nature and the nature of most deep passes by most QBs. Bruce and Holt made Warner look a lot better at the deep pass than he would look with TA.
You need tall physical receivers for those passes. If TA isn't in the open field, Foles should never throw it to him deep unless it's desperate and going for the PI.
I also thought TA had the speed to separate deep until I didn't. He has a horrible record catching the deep ball or separating after 30 yards. Dude's little legs pumping like Fred Flintstone's make him look faster than he is in a straight line. Just as Gurley's long graceful strides make him look slower.
TA is all YAC in my mind until he proves otherwise. Burst speed that is unfathomable. Slippery. Change of speed and direction that spins defenders to the ground. But straight line? It doesn't work.
That's crazy. Foles should just put the ball out in front of Austin. There are numerous other QBs in the NFL capable of doing it.
But yea, I'm sure who has recorded all of these long plays doesn't have great top-end speed:
56 yard run vs. Arizona (2013)
57 yard reception vs. Indy (2013)
63 yard reception vs. Carolina (2013)
65 yard run vs. Chicago (2013)
66 yard reception vs. San Francisco (2015)
73 yard punt return vs. San Diego (2014)
75 yard punt return vs. Seattle (2015)
78 yard punt return vs. Washington (2014)
81 yard reception vs. Indy (2013)
84 yard punt return vs. Dallas (2013)
98 yard punt return vs. Indy (2013)
That's 11 50+ yard plays in 3 years (including 5 75+ yard plays).
