Looked to me like DJ started jogging not expecting the ball. As much as I didn't like trading him away, that was a flaw of his.
But just not a smart decision to even throw there in the first place. With the conditions, adjusting one's route on the fly would've been a lot more difficult. Also, given how the situation played out, DJ would've needed to flatten his route a lot earlier to not enter a congested space. Finally, people must have tunnel vision because they are completely ignoring the actual throw. I'd say that had too much lead but more egregious, does not look like a throw that anticipated DJ flattening his route at all. Oh, and Curl had already read the route correctly and was moving along with DJ even before Caleb released it.
Even if DJ did everything right, the only thing that might've changed was DJ trying to tip the ball away from being intercepted.
