So as I remember both those two plays, it's kind of interesting to me to think about the arm strength argument...Allen does a good job of looking off the safety and since Sanders beats his man his ball actually doesn't need to be thrown so hard, but I think he waits for maximum separation and then lets it go w/ a ton of velocity for the 'easier' play
Jones' ball I would argue DOES actually need to be thrown harder because his route is a double move and the pump fake to set up Wallace (which worked btw, Agolhor was behind him) brings the safety into the picture because you are looking your guy down the whole route.
