thank you for this.
watching the game after they showed the replay on TV, i thought it was Yeldon's fault because he stopped on the play. however after watching it from this angle and in slo-mo, i do believe he was throwing to Beaser. Yeldon pulled up because he thought that too. we have seen many times Josh throwing it low to Beaser (whether on purpose or not) and that is what was happening here because of the coverage all around him. would have to see the All 22 to see where Allen's head is and hopefully his eyes are but just from this angle, the pick was on Allen.
remember, it was a broken play. they should have been running a scramble drill.
