I've watched this highlight several times. So many people want to criticize Young because he's doesn't throw down the field very much. However, if you watch this highlight and focus on the ball placement, It's a perfect throw. He leads Hubbard perfectly. He hits him in stride. He's full speed in a moment.
If he throws it too far in front he probably doesn't catch it or loses his balance enough that he gets tackled. Too far behind and he has to slow down a bit and doesn't get up to speed in time to score.
Bryce pinpoints a perfect throw, and Hubbard blows by everyone and scores.
It was a great play.
