Haener film looks better than Young.

Yeah, being honest, this seems a little enthusiastic. But since arm strength isn't the sole determinant of NFL QB success (hello Kyle Boller and others), it may not matter that much.
Maybe a little.

The real determinant is getting the ball there reliably and in stride. Accuracy trumps strength 90% of the time I guess. Jake is smart enough not to try any Josh Allen throws.

What hasn't been talked about enough is Jake's ability to scramble, find a receiver flashing open, and release the ball accurately all n a split second. He did that at least twice in the UCLA game. That's a great talent to have.
