Frost as HC Team Run/Pass Percentages (win%):
2016 UCF:  54/46 (.462)
2017 UCF:  54/46 (1.000)
2018 UNL:  54/46 (.333)
2019 UNL:  63/37 (.416)

Two things:
1 - it's best not to look at "even" as being 50/50....nearly all teams run more than they pass, due to play-call outcomes based on late-game score.  You pass a lot if you're behind with a chance to catch up, but you run a lot if you're ahead by a little or a lot, and if you're behind by a lot.  Based on EXTENSIVE research on this, I set "even" at about 58/42.  That's not scientific, just based on 1000+ team season ratios...it could easily be 56/44 or 60/40.  But it's certainly not 50/50.

2 - a team's record does affect play-calling, as the more a team loses, the further from their ideal goal of run/pass ratio they tend to stray (towards pass).  This makes the above pretty remarkable, that Frost's ratio remained the same through a losing season at UCF, an undefeated season at UCF, and a losing season at a new spot, Nebraska.

BUT, if you give any credence to my findings in #1 above, he's right in suggesting Frost has moved from being on the edge of balanced and pass-heavy (54/46) to the edge of balanced and run-heavy (63/37).  But to suggest he's been anywhere near run-heavy before 2019 would be incorrect. 

In 2018 he had sr WR's... 2019 really lacked non-slot WR's.   
thanks for doing the research.  Frost runs more of an oregon offense (or wants to run it).   He's a big believer in balance, though I'd say his big plays/chunk plays come out of the passing game (or did). 

Now.. if you are watching this year or last and saying that... I agree.   UNL has not seen Frost's offense.  We've seen a very conservative approach... which is not what he said he was bringing.   

Fearless.. Martinez is a decent runner who likes to pass the ball between the hashes.   He focuses on TE's and does a pretty good job in the screen game.  He can pass the ball long but seems to check down a lot.   He also stands tall in the pocket.   Luke is a very good runner who can create positive yards out of nothing.  He prefers passing outside the hashes and struggles with short passes or screens.   Not the arm either.   He dances in the pocket and has been late on reads...  He's seems to lead the team a little better. 

from my perspective we do not have a complete QB... And it will be tough to design a game plan with guys who are that different.   I'm not sure UNL has the WR's to make things easier either.   Hence, why they are run heavy and using the QB run so much.   Frost hasn't flipped the roster and bluntly, I don't see guys getting better to make things easier on the QB's either.   OL still struggles in pass pro... WR's still don't get open and don't win 1x1 battles.   QB's look worse than they are as a result.  

These all from the Gopher game in 2018 - Don't seem them anymore

WR seems to be a position that a young guy can learn quickly and contribute early

gotta be able to coach up a couple decent options in year 3

shoot!

Betts, Falck, and Martin getting catches today.  Brown playing last week.

not much time in the system

where's Warner and Hickman?  Too slow?

Passing isn't as easy without those FL skill position kids running all over the place...

this isn't exactly true. 

The QB is far more important than FL skill players. So is the scheme/play-caller.
