"quite often" is relative I suppose but even in this scenario I wouldn't consider 3 times per game "quite often". And I wouldn't consider 7 times per game "quite often" either.
"Quite deep" would be those 20 yard plus passes of which he only throws 3 per game, that is not "quite often" even if you take his relatively small number of overall passes per game which is only 22 per. And even if you include the 4 other passes per game he throws over 10 yards but not to the 20 yard threshold it still isn't all that many even if it is just under 1/3 of his throws.
But that is Utah's offense, they simply don't throw "quite deep" or even "quite often", they throw deep seldom and and only throw at all a fairly middling amount. But I do agree Huntley has been better than I thought he would be, I think I've said that enough to be clear about it.
