FWIW, this is how I view the Love/Heath incompletion:
Love is being payed $20+M; Heath's salary is about 2% of that.
It's much more incumbent on the QB to deliver an accurate throw than it is for a depth receiver to make an acrobatic catch.
I noticed a play the Rams ran last night that looked amazingly similar to the Heath attempt; same route, they both made their break from right-to-left, etc., but their receiver was much closer to the numbers as opposed to the sideline.
That makes me wonder if Heath didn't run a route correctly, since McVay's and MLF's offenses are supposed to be similar.
