When I first watched Haener highlights, I also wasn’t impressed by the arm strength. He made some solid deep throws, but I don’t remember seeing a lot of trademark NFL throws (which have a lower trajectory and more velocity).
For comparison, Dalton could float passes to Olave or Shaheed, but he couldn’t throw it on a line like Carr or Winston can.
I’m interested to see how his arm looks once the preseason games start.
