enough. A rollout should be shaped like a half circle if viewed from above. So if Hill is rolling to his left, he would start at 3 oclock....roll back to 6 and start heading upfield (from 9 to 6 to 3 when rolling to the right). IF he does this he has about half the field to throw to with power. The key is getting headed upfield so that the shoulders can rotate and the QB does not have to throw across his body. If you see the opposite shoulder pointed at the target as the throw starts, no matter which way the QB is rolling, you don't have to worry too much about he ball floating.

When a QB takes off on a flatter rollout, he significantly reduces the amount of field that he can throw without throwing across the body.

A lot of QBs can actually get more speed on the ball rolling to the left when they do it properly because they get more truck and shoulder rotation.

If you see a QB running flat or pretty close to parallel to the LOS, the ball is going to the sideline. The more it is thrown toward the middle of the field, the more it is going to float.
