Something to keep in mind wrt consistency vs explosiveness:
Last year, PSU had 161 drives (not counting kneel downs and what not)
In 72 of those drives they had at least one explosive play (20+ yards):
Of those 72 drives, they scored on 63 of them (87%)
In 89 of those drives they did not have an explosive play:
Of those 89 drives, they scored on 18 of them (20%)…..And 8 of those 19 scores came with a short field - where an explosive play may not have been possible.
(There is a reason CJF harps on "explosive plays" all the time

)
I expect that the figures were similar in 2016 (but I don't have those numbers handy).
The game has changed - and Moorhead most certainly was the perfect "adapter".
Accepting a few more "minus 2" plays, in a tradeoff for more frequent explosive plays.... as opposed to trying to always make at least "plus 3", with less frequent explosive plays..... is a tradeoff any smart coach would make.
Sure - - - you'd like to have both..... chunk out 5 yards on every first down AND hit on big explosive plays.... but there isn't any world were you get to have your cake and eat it too.
Generating explosive plays with maximum frequency is the key to winning - ESPECIALLY against better defenses (which simply don't allow you many long, bit-by-bit drives).
Which is why - among other things - Michigan's "Grind it Out", power-set Offense was abysmal against better teams.
How will PSU's offense fair in 2018? We will see.
