Here's a video of one:

Higgins breaks at 8 and rolls to 10 on the out.
Here are some stills that show Grayson's timing and anticipation on the throw:

You can see Grayson's back-foot planted with his front foot starting the stride into the throw and him pulling the ball back to start his throwing motion...this is 2-3 yards before Higgins starts to make his break

You can see the ball coming out of his hand right now right as Higgins is about to come out of the break

Ball placement isn't perfect but it's good...a tad high but placed in such a way that he doesn't lead Higgins out of bounds by putting it too far out in front but doesn't risk in interception by leaving it too far behind him...places it in such a way that Higgins can use his 6'2" frame to block the CB from getting to the ball and it gives Higgins a chance to stop, cut inside, and get the first down running after the catch
I also wanted to post this throw because it's one that is very memorable for me. Grayson made a ton of great throws into tight windows during his college career and this is one that won't be remembered because it wasn't caught. However, this is during the Utah game where Grayson's protection struggled mightily and Grayson was getting knocked around a lot. And yet, the guy continued to take hit after hit trying to make plays for his team. Here's the throw:

You see that Grayson has pressure in his face again as he releases the throw. Look at that window, it's non-existent. But he creates a window by dropping the ball over two defenders in the one spot he could place it where only his WR can get it. That's his stud WR, Rashard Higgins, and if Higgins catches that ball...he's strolling into the end-zone for six. That's not just a NFL throw...that's a throw you marvel at when a NFL QB makes it. And plays like that are why I think so highly of Grayson.
I know that people are concerned about his arm. It's functional but nowhere near elite. That all said, tell me that he doesn't look like he has a NFL arm on this throw:

But even better than the arm strength he showed, look what he does in the pocket. He feels the pressure, slides in the pocket to avoid it, creates a throwing lane, keeps his eyes down-field, and finds Rashard Higgins for a huge gain.
I understand that people aren't as high on this kid as I am and I understand why. He doesn't have a cannon and his release has a slight hitch in it (although it looked much improved at his Pro Day...we'll see if that carries over). But it's hard to deny his instincts in the pocket, his poise under pressure, and his ball placement.
And ultimately, I think those things are difference-makers at the next level. He has the instincts, mental acuity (or appears to), and ball placement to be a player at the next level. I want the Rams to draft him. Plus, he played for the Rams in college. Would only make sense for him to stay in Horns.
