i had WRs catch the ball in stride with a good QB like when i had Harrell. but the QB that was used in that video was rated a 77 or so. he wasn't that good. i also didn't user catch so maybe its different if you user catch the ball?
i have also overthrown WRs at times, usually results in a pick though.
but yeah, a lot of work is needed to make it look realistic with the WR/DB and the passing in general.
