That is true. But even on that play, that's a low percentage throw. Watch how the DB is closing in on the ball. The easier throw would be the post route. If when his back foot lands, he throws with anticipation to the post, it's an easier throw and likely TD.In general, I don't disagree... but sometimes you just have to trust your arm (Watson has a good arm, it isn't Mahomes but it ain't Shaub) and sling it. Closest play I could find in a hurry... Mahomes under pressure, throws it without being able to plant, longer throw than DW would have needed to make.
IMHO, it's just a risky throw.
