He's got an extremely live arm, and he's been timed at 4.60 in the 40 (to put that in context, Mahomes ran a 4.80 at his combine).
If you want more tape on him, I like this video as it shows a lot of non-td throws, but you may want to mute the guy (I have no idea who he is) and fast forward to the video. He can make every throw on the field.
Again, I have no idea what the next 5 months will bring, but if Maye is there at 3, I've seen no reason as of yet not to take him. He reminds me a lot of Josh Allen when he was in college, with much better decision making.

No video here, but it's a pretty good scouting report on him:

This is Colt McCoy breaking him down. It's long, over 40 minutes, but very in depth with video and breakdowns of the plays/defenses, etc:
