That is a very, very good number.
Yards per play is a great stat to look at.
For some people, 4 ypc and 8 ypa are sorta what should be considered "par" more or less. 8.9 yards per pass attempt is quite good.
Looks like Hendon didn't have enough attempts to qualify for the national leaders, but the 9.6 he averaged in 2019 would have put him at 7th in the nation (or tied for 6th).

His 8.9 in 2020 would have had him at about 18th:

EDIT on 10/3/2021:
Not sure why but ESPN's site is currently busted with the links to prior year yards per attempt rankings.
