Glad you had a chance to read it and weigh in with your thoughts.
Haener's arm length (29.75) is consistent with his overall smaller size, and as I said, I think it's his size that works the most against him (though it certainly doesn't mean he can't be successful, as we know.) For perspective, his arm is longer than Kyler Murray's (28.5) and less than an inch shorter than Bryce Young (30.5); all three of them being smaller quarterbacks.
Haener's measured velocity (57 MPH) from the combine (source
Ourlads) puts him near the top of his class. (You can scroll through to see QBs from other recent drafts.)
Dix has Josh Allen at 63, Ourlads has him at 62
Dix has Burrow at 56, Ourlads has NA
I really don't think Haener is going to have problems with velocity but I don't doubt there is room to improve with his mechanics. I'd expect his decision-making time and trigger time to improve with reps, but I thought he looked pretty composed for the most part in his first NFL action.

Ourlads’ Guide to the NFL Draft is the only source that gives the number for the quarterback’s velocity at the NFL Combine. Velocity is measured by a radar gun in miles per hour.
