Riley/Langsdorf/Pelini/Beck/Watson were actually running pretty similar offenses to what Scott Frost is running.
Scott Frost isn't returning Nebraska to smashmouth football, nor anything really Osborne related. He's bringing in the kind of high-octane, Chip Kelly West Coast big playbook hurry-up multiple offense Husker fans thought they hated until Scott Frost brought it to town. Frost might have gotten marginally more out of Tommy Armstrong, but we wouldn't have been wowed without an Adrian Martinez, who knows how to complete a bubble screen and other high-percentage touch passes.
Had this been any other coach on a 3-7 team, we'd be talking about why Nebraska abandoned those successful quarterback draws in the second half, why Ozigbo only got 11 carrries, and why we got cute by throwing the ball when we had the lead in the fourth quarter.
Frost is a better playcaller and Martinez is a better quarterback. But nothing really changes until we have a defense that isn't giving up 34 points a game.
Most of this is inaccurate. Especially the first sentence. The only one similar was Beck and he was trying to mold his offense after Oregon's. And almost no Husker fans hated or even disliked what they saw out of Oregon's or UCF's offense. Not sure where you are pulling that idea from.
Also, in 2017, UCF was #71 for highest pass-to-run ratio in the country. Nebraska with Riley's QB was #8.
In 2016, UCF was #53 (Nebraska #80) - with Armstrong they passed it less for very obvious reasons. This was an anomaly for that coaching staff.
In 2015, Oregon was #104 (Nebraska #55)
In 2014, Oregon was #94 (Oregon St. #10, Nebraska #112)
In 2013, Oregon was #91 (Oregon St. #3, Nebraska #105)
This year, Nebraska is #72
And to add to that, Mario Verduzco has stated that Martinez reminded him of Marcus Mariota in his high school film. That's the kind of guy they want, and they got him, and that's who the QB was with those pass ratio rankings 2013-2014.
Another inaccuracy in your post are what we would be saying if it wasn't Frost. I'm sure there is some of that going on but there were complaints about game management and playcalling in the first 5-6 games. But the fact of the matter is most people gave Riley a chance his first season, too.
