Kody was running his route to the corner of the end zone, which is where that ball was supposed to be. If we're assigning blame, it was 95% Jake, and 5% Kody, and even that's being generous for Jake.
When a ball is nowhere close to where it was supposed to be, that's 100% on the QB. Hopefully Jake Retzlaff would agree. He seems like the kind of QB that would. And I bet if you asked Jake, he'd tell you he was expecting himself to throw that ball where it was supposed to be and that he wasn't intending to toss up a jump ball that was going to fall well short of his receiver's route.
Epps had a step. He was open. Put the ball where it was supposed to be and it's a TD.
Epps wasn't playing center field, he was running his route, and it's a lot harder to adjust the route in real time when the ball doesn't end up being where he's expecting it to be.
Put another way, if that long ball to Chase on the trick play had also been that short of where it was supposed to be, that ball also gets intercepted. Would you be blaming Chase? Would you be claiming if only Kody had been running that route instead of Chase?
