Sorry
@jrry32 I usually agree with your takes but I think you have it wrong here. And you of all trying to sneak a bad example by me. A Boldin 6' 1" 220 S Bailey 5' 10 195.
They are just different players not comparable except they play wideout.
If Bailey (I know he is a darling here) was an advancement over his peers he would play and see the ball.
I hope this happens sooner than later.
A wide receivers space or separation is created by commitment to the route and speed out of the breaks. Size can also contribute.
The QB analogy is a Can O Worms, some can throw a receiver open some Don't and some do on occasion.
