Frost can’t throw the players from the previous regimes under the bus and expect them to “buy in”. It creates division. It’s that simple. Besides, they are his players now and he has now had them for 2 years. If they were not good enough to obtain a winning record and reach a bowl game in 2019, that is the fault of the current coaching staff not the previous one.
What should he do, create a circle around the campfire and sing songs? Those players HAVE to know they haven't met the expectations for a player at the University of Nebraska. The staff has made plenty of mistakes, but this is about the players and their accountability. A coach can call the wrong play, and that's not good, but players are the guys missing blocks, lanes or reads that cause plays to fail more often than not. If Scott called every play perfectly, that's still not going to change players executing at an abysmal level.
There are people who rise to a challenge, and those who shrink, and we seem to think we need to coach solely for the shrinkers on the roster. If there was any mistake in messaging, it was not conveying to the team that they all have the ability to become contributing players (though we know that isn't true). When you see how some made dramatic improvements to the players they were originally, you have to feel that message was understood by at least some of the players. Those that have chosen to feel a victim instead of rising to the challenge might be guys we just aren't going to be rehabilitating, but running off. Remind us again just how well they handled the positive environment of Riley? Did they push themselves? Did they act disappointed in their failures? It seems we have some folks that think we need to continually adapt our program around the whim and moods of the players, which I'm not seeing as having had great success in the past.
