QB is the hardest position to play. Making the right read, timing the throw just right. All while the defense gives you different looks, you hope the O-line can block, all the receivers are running the right routes/ options/ reads and that the backs pick up the right assignment and you know the other team pay someone big $ just to take you down and he's coming to take you down with the hope that that hit makes it onto a highlight reel.
So there's an acrimonious split because a QB missed a WR.
So what. How many times as receivers have you come back to the huddle claiming you were "open"...open to find grass in the QB's helmet, that the other receiver caught the pass or that on film, you weren't even open...
It'll be interesting in Dallas at least.
