I've noticed over the past couple years that his deep passes have deteriorated

His deep passes used to be right on the money and now they seem to fall short

What I base this on is; can anyone remember 2009 vs the patriots, brees threw what I thought what the best pass I have ever seen in my life, play action 49 yard pass that literally hit meachems hands without him extending

Now a days I see drew over throw lance Moore when he's wide open, happened a couple times this season, half of drews pick are ones he throws behind receivers
I'm in no way saying his arm is done, but the deep pass he threw to joe Morgan vs ATL that was picked, seemed to lack zip and drew would normally know not to throw that ball when the safeties are playing deep
