Exactly on point with the pump fake. It was not needed in this situation and actually hindered the play.You can find plays from all qbs where a pass was over thrown or under thrown. Or where you can say if he throwns ih here instead of there it's a td. If you have a play like that from a qb, where say Jamar Chase slows a bit and then wins a battle for a jump ball or even gets ran into by the defender for an interference call nobody questions Burrows arm strength. Some people will even go as far as praising Burrow for the pass. I bet I can find plays where Mark Clayton slowed or stopped on some routes and then won a contested jump ball from Marino. I know I can find some from Orande Gadsen. Nobody ever said it was because Marino's arm was lacking.
My thing is that it's often attributed to Tua's arm when plays like the one shown in the example pops up.
However if he throws the ball a bit earlier hits Hill in stride, it might be good for a td and nobody says a thing. There's no questions about arm strength. So is the issue really arm strength or timing between qb and wrs? When you have a qb that leans heavy on timing with smaller wrs and you have wrs that are sometimes late on routes and other times early you're going to have plays that look like the one that's shown.
One thing with Tua is, if his mechanics aren't perfect, his throws suffer immensely. I think if he threw to Hill right away without the pump fake, he would've hit him in that perfect window between the CB and the safety over the top...
